[ASTMatcher] Correct memoization bug ignoring direction (descendants or ancestors)
Summary:
In ASTMatcher, when we have `has(...)` and `hasParent(...)` called with the same internal matcher on the same node, the memoization process will mix-up the two calls because the direction of the traversal is not part of the memoization key.
This patch adds this information.

[MSP430] Enable some basic support for debug information
This commit technically permits LLVM to emit the debug information for ELF files for MSP430 architecture. Aside from this, it only defines the register numbers as defined by part 10.1 of MSP430 EABI specification (assuming the 1-byte subregisters share the register numbers with corresponding full-size registers).
This commit was basically tested by me with TI-provided GCC 8.3.1 toolchain by compiling an example program with `clang` (please note manual linking may be required due to upstream `clang` not yet handling the `-msim` option necessary to run binaries on the GDB-provided simulator) and then running it and single-stepping with `msp430-elf-gdb` like this:
```
$sysroot/bin/msp430-elf-gdb ./test -ex "target sim" -ex "load ./test"
(gdb) ... traditional GDB commands follow ...
```
While this implementation is most probably far from completeness and is considered experimental, it can already help with debugging MSP430 programs as well as finding issues in LLVM debug info support for MSP430 itself.
One of the use cases includes trying to find a point where UBSan check in a trap-on-error mode was triggered.
The expected debug information format is described in the [MSP430 Embedded Application Binary Interface](http://www.ti.com/lit/an/slaa534/slaa534.pdf) specification, part 10.

[DebugInfo] Explicitly permit addr_size = 0x02 when parsing DWARF data
Current LLVM implementation uses `MCAsmInfo::CodePointerSize` as addr_size when emitting the DWARF data. llvm-dwarfdump, on the other hand, handles `addr_size`s of 4 and 8 properly and considers all other sizes as an error. This works for most of mainline targets except for MSP430 and AVR.
msp430-gcc v8.3.1 emits DWARF32 with addr_size = 4 (DWARF32 does not imply addr_size = 4, 32 refers to internal offset width of 4 bytes) that is handled by llvm-dwarfdump already. Still, emitting 2-byte target pointers on MSP430 seems correct as well (but not for MSP430X that is supported by msp430-gcc but not by LLVM and has 20-bit address space).

[lld-macho] Refactor segment/section creation, sorting, and merging
Summary:
There were a few issues with the previous setup:
1. The section sorting comparator used a declarative map of section names to
determine the correct order, but it turns out we need to match on more than
just names -- in particular, an upcoming diff will sort based on whether the
S_ZERO_FILL flag is set. This diff changes the sorter to a more imperative but
flexible form.
2. We were sorting OutputSections stored in a MapVector, which left the
MapVector in an inconsistent state -- the wrong keys map to the wrong values!
In practice, we weren't doing key lookups (only container iteration) after the
sort, so this was fine, but it was still a dubious state of affairs. This diff
copies the OutputSections to a vector before sorting them.
3. We were adding unneeded OutputSections to OutputSegments and then filtering
them out later, which meant that we had to remember whether an OutputSegment
was in a pre- or post-filtered state. This diff only adds the sections to the
segments if they are needed.
In addition to those major changes, two minor ones worth noting:
1. I renamed all OutputSection variable names to `osec`, to parallel `isec`.
Previously we were using some inconsistent combination of `osec`, `os`, and
`section`.
2. I added a check (and a test) for InputSections with names that clashed with
those of our synthetic OutputSections.

template instantiation bailed out instead of reporting the error,
these instantiations could even be postponed, which would make them

Enable this by default for clang-cl. MSVC creates PCHs by compiling
them using an empty .cpp file, which means templates are instantiated
while building the PCH and so the .h needs to be self-contained,

with MSVC anyway. So the option being enabled for clang-cl matches this.

potentially helping to reduce the number of register moves needed as the

CodegenPrepare as it naturally straddles basic blocks.
The alorithm just looks from phi nodes, looking at uses and operands for
a collection of nodes that all together are bitcast between float and
integer types. We record visited phi nodes to not have to process them
more than once. The whole subgraph is then replaced with a new type.
Loads and Stores are bitcast to the correct type, which should then be
folded into the load/store, changing it's type.
This comes up in the biquad testcase due to the way MVE needs to keep
values in integer registers. I have also seen it come up from aarch64
partner example code, where a complicated set of sroa/inlining produced
integer phis, where float would have been a better choice.

[ValueTracking, BasicAA] Don't simplify instructions

expensive, but has little effect in practice. This patch removes
the SimplifyInstruction call(), and replaces it with a check for
single-argument phis (which can occur in canonical IR in LCSSA
form), which is the only useful simplification case I was able to
identify.
At O3 the geomean CTMark improvement is -1.7%. The largest

no code size difference (PAQ8p, Ptrdist), which indicates that
the simplification only ends up being useful very rarely. (I would

but wasn't able to spot it looking at transformation logs.)
The AMDGPU test case that is update was using two selects with
undef condition, in which case GetUnderlyingObject will return
the first select operand as the underlying object. This will of
course not happen with non-undef conditions, so this was not
testing anything realistic. Additionally this illustrates potential
unsoundness: While GetUnderlyingObject will pick the first operand,
the select might be later replaced by the second operand, resulting

This patch adds SimplifyDemandedVectorEltsForTargetShuffle (a custom x86 helper) to first try SimplifyDemandedVectorElts (which we already do) and then constant pool simplification to help mark undefined elements.
To prevent lowering/combines infinite loops, we only handle basic constant pool loads instead of creating new BUILD_VECTOR nodes for lowering - e.g. we don't try to convert them to broadcast/vzext_load - there might be some benefit to this but if so I'd rather we come up with some way to reuse existing code than reimplement a lot of BUILD_VECTOR code.

Summary:
Add call site location info into inline remarks so we can differentiate inline sites.
This can be useful for inliner tuning. We can also reconstruct full hierarchical inline

differentiate SampleProfileLoader inline from CGSCC inline.

[CMake] Fix runtimes build for host Windows (default target)
When building runtimes, the compiler name (e.g. clang, clang-cl) is set based on

This mechanism doesn't work well if the target is Windows host.
`runtime_default_target()`/`builtin_default_target()` doesn't provide a way
to specify `CMAKE_SYSTEM_NAME` and doesn't set it either.
