Summary:
Since these files depend on the built python modules, they need to use
the right python binary to run them. So use configure_file
to set the right shebang line.

We cannot override the DWARF version in the CFLAGS_EXTRA because they
are used by tests that explicitly build without debug info. Instead, we
pass them through the regular CFLAGS.

In particular, make TinyPtrVector<PtrIntPair<T *, 1>> work. Remove all
unnecessary assumptions that the element type has a formal "null"
representation. The important property to maintain is that
default-constructed element type has the same internal representation
as the default-constructed PointerUnion (all zero bits).
Remove the incorrect recursive behavior from
PointerUnion::isNull. This was never generally correct because it only
recursed over the first type parameter. With variadic templates it's
completely unnecessary.

Add a GlobalISel equivalent for the logical_imm32_XFORM and logical_imm64_XFORM
SDNodeXForms in AArch64InstrFormats.td.
- Add select-logical-imm.mir, which contains tests for each imported pattern.
- Update select-pr32733.mir and select-scalar-shift-imm.mir, since they now

Summary:
When inserting a new Def, and inserting Phis in the IDF when needed,
also mark the already existing Phis in the IDF as non-optimized, since
these may need fixing as well.
In the test attached, there is a Phi in the IDF that happens to be
trivial, and is wrongfully removed by the call to getLastDef that
follows. This is a valid situation and the existing IDF Phis need to
marked as "may need fixing" as well.

This patch fixes a bunch of -Wdocumentation warnings in Utility. I'm
sure there are still a bunch outdated comments left, but this fixes the
most flagrant inconsistencies that the compiler understands.

This adds GlobalISel equivalents for the following from AArch64InstrFormats:
- arith_shifted_reg32
- arith_shifted_reg64
And partial support for
- logical_shifted_reg32
- logical_shifted_reg32
The only thing missing for the logical cases is support for rotates. Other than
the missing support, the transformation is identical for the arithmetic shifted
register and the logical shifted register.
Lots of tests here:
- Add select-arith-shifted-reg.mir to show that we correctly select add and
sub instructions which use this pattern.
- Add select-logical-shifted-reg.mir to cover patterns which are not shared
between the arithmetic and logical cases.
- Update addsub-shifted.ll to show that we correctly fold shifts into
adds/subs.
- Update eon.ll to show that we can select the eon instruction by folding xors.

I also had to add a new combine to X86's combineExtractSubvector to prevent a regression.
This helps our vXi1 code see the full concat operation and allow it optimize undef to a zero if there is already a zero in the concat. This helped us use a movzx instead of an AND in some of the tests. In those tests, one concat comes from SelectionDAGBuilder and the second comes from type legalization of v4i1->i4 bitcasts which uses an additional concat. Though these changes weren't my original motivation.
I'm looking at making X86ISelLowering's narrowShuffle emit a concat_vectors instead of an insert_subvector since concat_vectors is more canonical during early DAG combine. This patch helps prevent a regression from my experiments with that.

Overloaded intrinsics can use iPTRAny in used/input operands.
The GlobalISelEmitter doesn't know that these are pointers, so it treats them
as scalars. As a result, these intrinsics can't be imported.
This teaches the GlobalISelEmitter to recognize these as pointers rather than
scalars.

Adds Wrapper classes for MCSymbol and MCSection into the XCOFF target
object writer. Also adds a class to represent the top-level sections, which we
materialize in the ObjectWriter.
executePostLayoutBinding will map all csects into the appropriate
container depending on its storage mapping class, and map all symbols
into their containing csect. Once all symbols have been processed we
- Assign addresses and symbol table indices.
- Calaculte section sizes.
- Build the section header table.
- Assign the sections raw-pointer value for non-virtual sections.
Since the .bss section is virtual, writing the header table is enough to
add support. Writing of a sections raw data, or of any relocations is
not included in this patch.
Testing is done by dumping the section header table, but it needs to be
extended to include dumping the symbol table once readobj support for
dumping auxiallary entries lands.

Calling a pure virtual method during construction or destruction
is undefined behavior. It's worth it to warn about it by default.
That part is now known as the cplusplus.PureVirtualCall checker.
Calling a normal virtual method during construction or destruction
may be fine, but does behave unexpectedly, as it skips virtual dispatch.
Do not warn about this by default, but let projects opt in into it
by enabling the optin.cplusplus.VirtualCall checker manually.
Give the two parts differentiated warning text:
Before:
Call to virtual function during construction or destruction:
Call to pure virtual function during construction
Call to virtual function during construction or destruction:
Call to virtual function during destruction
After:
Pure virtual method call:
Call to pure virtual method 'X::foo' during construction
has undefined behavior
Unexpected loss of virtual dispatch:
Call to virtual method 'Y::bar' during construction
bypasses virtual dispatch
Also fix checker names in consumers that support them (eg., clang-tidy)
because we now have different checker names for pure virtual calls and
regular virtual calls.
Also fix capitalization in the bug category.

This avoids producing an output file if errors appeared late in the
linking process (e.g. while fixing relocations, or as in the test,
while checking for multiple resources). If an output file is produced,
build tools might not retry building it on rebuilds, even if a previous
build failed due to the error return code.

When running tests on windows, invoking "llc -march=<arch>" will
implicitly use windows as the target os, making these tests misbehave
after this change.
Fix the issue by using more specific -mtriple values instead of plain
-march in these tests.
This should hopefully fix buildbot failures like

This patch fixes https://github.com/google/sanitizers/issues/703
On a Graviton-A1 aarch64 machine with 48-bit VMA,
the time spent in LSan and ASan reduced from 2.5s to 0.01s when running
clang -fsanitize=leak compiler-rt/test/lsan/TestCases/sanity_check_pure_c.c && time ./a.out
clang -fsanitize=address compiler-rt/test/lsan/TestCases/sanity_check_pure_c.c && time ./a.out
With this patch, LSan and ASan create both the 32 and 64 allocators and select
at run time between the two allocators following a global variable that is
initialized at init time to whether the allocator64 can be used in the virtual
address space.

Summary:
StringMap is used for storing call target to frequency map for AutoFDO. However the iterating order of StringMap is non-deterministic, which leads to non-determinism in AutoFDO profile output. Now new API getSortedCallTargets and SortCallTargets are added for deterministic ordering and output.
Roundtrip test for text profile and binary profile is added.
