IE throws errors while using key and mouse navigation through the error path tips.
querySelectorAll method returns NodeList. NodeList belongs to browser API. IE doesn't have forEach among NodeList's methods. At the same time Array is a JavaScript object and can be used instead. The fix is in the converting NodeList into Array and keeps using forEach method as before.
Checked in IE11, Chrome and Opera.

alloc/dealloc/copies.
Add options to LinalgPromotion to use callbacks for implementating the
allocation, deallocation of buffers used for the promoted subviews,
and to copy data into and from the original subviews to the allocated
buffers.
Also some misc. cleanup of the code.

Modifying the loop nest builder for generating scf.parallel loops to
not generate scf.parallel loops for non-parallel iterator types in
Linalg operations. The existing implementation incorrectly generated
scf.parallel for all tiled loops. It is rectified by refactoring logic
used while lowering to loops that accounted for this.

This fixes a bug in `tryOptArithImmedIntegerCompare`.
It is unsafe to update the predicate on a MachineOperand when optimizing a
G_ICMP, because it may be used in more than one place.
For example, when we are optimizing G_SELECT, we allow compares which are used
in more than one G_SELECT. If we modify the G_ICMP, then we'll break one of
the G_SELECTs.
Since the compare is being produced to either
1) Select a G_ICMP
2) Fold a G_ICMP into an instruction when profitable
there's no reason to actually modify it. The change is local to the specific
compare.
Instead, pass a `CmpInst::Predicate` to `tryOptArithImmedIntegerCompare` which
can be modified by reference.

This op extracts an extent from a shape.
This also is the first op which constant folds to shape.const_size,

seem to always need folders for the constant folding infra to work).

Summary:
preallocated and musttail can work together, but we don't want to call
@llvm.call.preallocated.setup() to modify the stack in musttail calls.
So we shouldn't have the "preallocated" operand bundle when a
preallocated call is musttail.
Also disallow use of preallocated on calls without preallocated.
Codegen not yet implemented.

Summary:
Based on comments received in D80415 pertinent to test case format, the following fixes are provided to other tests in 'aix-ld.c' for the sake of consistency and readability,
- Align flags in RUN directives vertically.
- Align patterns in CHECK directives vertically.
- Remove the ‘-o %t.o’ as it’s unnecessary for tests with ‘-###’.
- Fix typos in comments.

If you remember the mail [1] I sent out about how I envision the future of the
already existing checkers to look dependencywise, one my main points was that no
checker that emits diagnostics should be a dependency. This is more problematic
for some checkers (ahem, RetainCount [2]) more than for others, like this one.
The MallocChecker family is a mostly big monolithic modeling class some small
reporting checkers that only come to action when we are constructing a warning
message, after the actual bug was detected. The implication of this is that
NewDeleteChecker doesn't really do anything to depend on, so this change was
relatively simple.
The only thing that complicates this change is that FreeMemAux (MallocCheckers
method that models general memory deallocation) returns after calling a bug
reporting method, regardless whether the report was ever emitted (which may not
always happen, for instance, if the checker responsible for the report isn't
enabled). This return unfortunately happens before cleaning up the maps in the
GDM keeping track of the state of symbols (whether they are released, whether
that release was successful, etc). What this means is that upon disabling some
checkers, we would never clean up the map and that could've lead to false
positives, e.g.:
error: 'warning' diagnostics seen but not expected:
File clang/test/Analysis/NewDelete-intersections.mm Line 66: Potential leak of memory pointed to by 'p'
File clang/test/Analysis/NewDelete-intersections.mm Line 73: Potential leak of memory pointed to by 'p'
File clang/test/Analysis/NewDelete-intersections.mm Line 77: Potential leak of memory pointed to by 'p'
error: 'warning' diagnostics seen but not expected:
File clang/test/Analysis/NewDelete-checker-test.cpp Line 111: Undefined or garbage value returned to caller
File clang/test/Analysis/NewDelete-checker-test.cpp Line 200: Potential leak of memory pointed to by 'p'
error: 'warning' diagnostics seen but not expected:
File clang/test/Analysis/new.cpp Line 137: Potential leak of memory pointed to by 'x'
There two possible approaches I had in mind:
Make bug reporting methods of MallocChecker returns whether they succeeded, and
proceed with the rest of FreeMemAux if not,
Halt execution with a sink node upon failure. I decided to go with this, as
described in the code.
As you can see from the removed/changed test files, before the big checker
dependency effort landed, there were tests to check for all the weird
configurations of enabled/disabled checkers and their messy interactions, I
largely repurposed these.

Similarly to other patches of mine, I'm trying to uniformize the checker
interface so that dependency checkers don't emit diagnostics. The checker that
made me most anxious so far was definitely RetainCount, because it is definitely
impacted by backward compatibility concerns, and implements a checker hierarchy
that is a lot different to other examples of similar size. Also, I don't have
authority, nor expertise regarding ObjC related code, so I welcome any
objection/discussion!

Summary:
This patch makes the following changes to SanCov and its complementary Python script in order to resolve issues pertaining to non-UNIX file paths in JSON symbolization information:
* Convert all paths to use forward slash.
* Update `coverage-report-server.py` to correctly handle paths to sources which contain spaces.
* Remove Linux platform restriction for all SanCov unit tests. All SanCov tests passed when ran on my local Windows machine.

Summary:
A struct argument can be passed-by-value to a callee via a pointer to a
temporary stack copy. Add support for emitting an entry value DBG_VALUE
when an indirect parameter DBG_VALUE becomes unavailable. This is done
by omitting DW_OP_stack_value from the entry value expression, to make
the expression describe the location of an object.

I think the current code dealing with connecting the unrolled iterations
is a bit more complicated than necessary currently. To connect the
unrolled iterations, we have to update the unrolled latch blocks to
branch to the header of the next unrolled iteration.
We need to do this regardless whether the latch is exiting or not.
Additionally, we try to turn the conditional branch in the exiting block
to an unconditional one. This is an optimization only; alternatively we
could leave the conditional branches in place and rely on other passes
to simplify the conditions.
Logically, this is a separate step from connecting the latches to the
headers, but it is convenient to fold them into the same loop, if the
latch is also exiting. For headers (or other non-latch exiting blocks,
this is done separately).
Hopefully the patch with additional comments makes things a bit clearer.

Don't run tests that use address sanitizer inside an address-sanitized
LLDB. The tests don't support that configuration. Incidentally they
were skipped on green dragon for a different reason, so this hasn't
come up there before.
I'm guessing this was a holdover from when 0 was an invalid stack
pointer, but surprised nobody has discovered this before.
Also don't allow offset folding for -1 pointers, since it looks weird
to partially fold this.
This revision expands the types of vector contractions that can be lowered to vector.outerproduct.
All 8 permutation cases are support.
The idiomatic manipulation of AffineMap written declaratively makes this straightforward.
In the process a bug with the vector.contract verifier was uncovered.
The vector shape verification part of the contract op is rewritten to use AffineMap composition.
One bug in the vector `ops.mlir` test is fixed and a new case not yet captured is added
to the vector`invalid.mlir` test.

Summary:
We were not detecting declaring multiple interfaces to the same procedure.
Also, we were not handling the initialization of entitiies where the associated
Symbol had previously had errors.
I added the function `IsInterfaceSet()` to ProcEntityDetails to see if
the value of `interface_` had been previously set. I then checked this
function before calling set_interface() and emitted an error message if
the interface was already set.
Also, in situations where we were emitting error messages for symbols, I
set the Error flag on the Symbol. Then when performing initialization
on the Symbol, I first check to see if the Symbol had an error.
