Summary:
Add definitions for the KernelLoaderSpec and MultiKernelLoaderSpec
classes to StreamExecutor. Instances of these classes are generated by the
compiler in order to provide host code with a handle to device code.

It is possible for the value map to not have an entry for some value

I don't have a testcase, this is fall-out from a buildbot.

Due to internal reuse of buffers in the RenderScript runtime by the system allocator,
comparing pointers is not a safe way to check whether an allocation is tracked by lldb.
This change updates the lldb RenderScript internal hook callback to properly
identify and remove old allocations that had have an address that is currently
being tracked.
This change also removes the need for `lldb_private::renderscript::LookupAllocation`
to take a `create` flag, as this is now always the case.

We were able to figure out that the result of a call is some constant.
While propagating that fact, we added the constant to the value map.
This is problematic because it results in us losing the call site when
processing the value map.
This fixes PR28802.

MappedBlockSTream can work with any sequence of block data where
the ordering is specified by a list of block numbers. So rather
than manually stitch them together in the case of the FPM, reuse
this functionality so that we can treat the FPM as if it were
contiguous.

``num_params`` was unused in RenderScript ABI fixup pass ``cloneToStructRetFnTy``
and was only used in an `assert()` that the number of function parameters for the cloned
function was correct.
Now we actually use this variable, rather than recomputing it, and avoid the unused variable
warning when building without asserts enabled.

When expanding FP constants, we attempt to shrink doubles to floats and perform an extending load.
However, on SystemZ, and possibly on other targets (I've only confirmed the problem on SystemZ), the FP extending load instruction may convert SNaN into QNaN, or may cause an exception. So in the general case, we would still like to shrink FP constants, but SNaNs should be left as doubles.

When the same base address is used to load two different data types, LSR
would assume a memory type of "void". This type is not sized and has no
alignment information. Checking for it causes a crash.

Previously, we would search through all replacements when inserting a
new one to check for overlaps. Instead, make use of the fact that we
already have a set of replacments without overlaps to find the potential

Otherwise, we would try to re-optimize them with Polly-ACC and possibly even
generate kernels that try to offload themselves, which does not work as the
GPURuntime is not available on the accelerator and also does not make any

Previously we supported only sorting by name.
When there are nested section sorting commands in linker script, there can be at most 1
level of nesting for section sorting commands.
SORT_BY_NAME (SORT_BY_ALIGNMENT (wildcard section pattern)). It will sort the input
sections by name first, then by alignment if 2 sections have the same name.
SORT_BY_ALIGNMENT (SORT_BY_NAME (wildcard section pattern)). It will sort the input
sections by alignment first, then by name if 2 sections have the same alignment.
SORT_BY_NAME (SORT_BY_NAME (wildcard section pattern)) is treated the same as SORT_
BY_NAME (wildcard section pattern).
SORT_BY_ALIGNMENT (SORT_BY_ALIGNMENT (wildcard section pattern)) is treated the
same as SORT_BY_ALIGNMENT (wildcard section pattern).
All other nested section sorting commands are invalid.
Patch implements that all above.

This also makes the repeating pass wrapper assignable. Mildly
unfortunate as it means we can't use a const member for the int, but
that is a really minor invariant to try to preserve at the cost of loss
of regularity of the type. Yet another annoyance of the particular C++
object / move semantic model.

manager.
While this has some utility for debugging and testing on its own, it is
primarily intended to demonstrate the technique for adding custom
wrappers that can provide more interesting interation behavior in
a nice, orthogonal, and composable layer.
Being able to write these kinds of very dynamic and customized controls
for running passes was one of the motivating use cases of the new pass
manager design, and this gives a hint at how they might look. The actual
logic is tiny here, and most of this is just wiring in the pipeline
parsing so that this can be widely used.
I'm adding this now to show the wiring without a lot of business logic.
This is a precursor patch for showing how a "iterate up to N times as
long as we devirtualize a call" utility can be added as a separable and
composable component along side the CGSCC pass management.

Summary:
We also add a test to show what currently happens when we create a
section per function and emit an xray_instr_map. This illustrates the
relationship (or lack thereof) between the per-function section and the
xray_instr_map section.
We also change the code generation slightly so that we don't always
create group sections, but rather only do so if a function where the
table is associated with is in a group.
Also in this change:
- Remove the "merge" flag on the xray_instr_map section.
- Test that we're generating the right table for comdat and non-comdat functions.

IfConversion used to always add the undef flag when adding a use operand
on a newly predicated instruction. This would be an operand for the register
being conditionally redefined. Due to the undef flag, the liveness of this
register prior to the predicated instruction would get lost.
This patch changes this so that such use operands are added only when the
register is live, without the undef flag.
This was reverted but pushed again now, for details follow link below.

Mergeable sections with size zero are useless because they don't
actually contain data, and therefore there's no merit ot merge them.
However, in reality, there are object files in the wild containing
such sections. Currently, LLD can't handle them proerply.
This patch makes LLD to handle such sections as if they are non-
mergeable to fix the issue.

reason about and less error prone.
The core idea is to fully parse the text without trying to identify
passes or structure. This is done with a single state machine. There
were various bugs in the logic around this previously that were repeated
and scattered across the code. Having a single routine makes it much
easier to fix and get correct. For example, this routine doesn't suffer
from PR28577.
Then the actual pass construction is handled using *much* easier to read
code and simple loops, with particular pass manager construction sunk to
live with other pass construction. This is especially nice as the pass
managers *are* in fact passes.
Finally, the "implicit" pass manager synthesis is done much more simply
by forming "pre-parsed" structures rather than having to duplicate tons
of logic.
One of the bugs fixed by this was evident in the tests where we accepted
a pipeline that wasn't really well formed. Another bug is PR28577 for
which I have added a test case.
The code is less efficient than the previous code but I'm really hoping
that's not a priority. ;]
