Summary:
This matches ELF.
This makes the number of ASan failures under the new pass manager on
Windows go from 18 to 1.
Under the old pass manager, the ASan module pass was one of the very
last things run, so these globals didn't get removed due to GlobalOpt.
But with the NPM the ASan module pass that adds these globals are run
much earlier in the pipeline and GlobalOpt ends up removing them.

An initial patch adding combineSetCCMOVMSK to simplify MOVMSK and its vector input based on the comparison of the MOVMSK result.
This first stage just adds support for some simple MOVMSK(PACKSSBW()) cases where we remove the PACKSS if we're comparing ne/eq zero (any_of patterns), allowing us to directly compare against the v8i16 source vector(s) bitcasted to v16i8, with suitable masking to take into account of which signbits are valid.
Future combines could peek through further PACKSS, target shuffles, handle all_of patterns (ne/eq -1), optimize to a PTEST op, etc.

Summary:
According to the comments, we want to convert the profile into two binary formats, and then into the md5text format.
We seems to have ignored the intermediate files.
This patch uses them to complete the full roundtrips.

Improve consistency when printing test results:
Previously we were using different labels for group names (the header
for the list of, e.g., failing tests) and summary count lines. For
example, "Failing Tests"/"Unexpected Failures". This commit changes lit
to label things consistently.
Improve wording of labels:
When talking about individual test results, the first word in
"Unexpected Failures", "Expected Passes", and "Individual Timeouts" is
superfluous. Some labels contain the word "Tests" and some don't.
Let's simplify the names.
Before:
```
Failing Tests (1):
...
Expected Passes : 3
Unexpected Failures: 1
```
After:
```
Failed Tests (1):
...
Passed: 3
Failed: 1
```

This patch updates TargetLoweringBase::computeRegisterProperties and
TargetLoweringBase::getTypeConversion to support scalable vectors,
and make the right calls on how to legalise them. These changes are required
to legalise both MVTs and EVTs.

Summary:
Add regression tests of asmparser, mccodeemitter, and disassembler for
branch instructions. In order to support them, we enhance asmparser
by adding splitting mnemonic mechanism, e.g. "bgt.l.t" into "b", "gt",
and ".l.t", and parsing mechanism for AS style memory addressing.
We also implment encoding and decoding mechanism for branch instructions.

Current implementation of emitPatchpoint() is very inefficient:
for every FrameIndex operand if creates new MachineInstr with
that operand expanded and all other copied as is.
Since PATCHPOINT/STATEPOINT instructions may have *a lot* of
FrameIndex operands, we end up creating and erasing many
machine instructions. But we can do it in single pass, with only
one new machine instruction generated.

Differential Revision: https://reviews.llvm.org/D81081
Summary:
This patch adds legalisation of extensions where the operand
of the extend is a legal scalable type but the result is not.
EXTRACT_SUBVECTOR is used to split the result, before
being replaced by target-specific [S|U]UNPK[HI|LO] operations.
For example:
```
zext <vscale x 16 x i8> %a to <vscale x 16 x i16>
```
should emit:
```
uunpklo z2.h, z0.b
uunpkhi z1.h, z0.b
```

This patch addresses the comment in [D80972](https://reviews.llvm.org/D80972#inline-744217).
Before this patch, the initial length field of .debug_aranges section should be declared as:
```
## 32-bit DWARF
debug_aranges:
- Length:
TotalLength: 0x20
Version: 2
...
## 64-bit DWARF
debug_aranges:
- Length:
TotalLength: 0xffffffff
TotalLength64: 0x20
Version: 2
...
```
After this patch:
```
## 32-bit DWARF
debug_aranges:
- [[Format: DWARF32]] ## Optional
Length: 0x20
Version: 2
...
## 64-bit DWARF
debug_aranges:
- Format: DWARF64

Version: 2
```
Current implementation of generating DWARF64 .debug_aranges section is buggy. A follow-up patch will improve it and add test cases for DWARF64.

It should not be necessary to use weak linkage for these. Doing so
implies interposablity and thus PIC generates indirections and
dynamic relocations, which are unnecessary and suboptimal. Aside
from this, ASan instrumentation never introduces GOT indirection
relocations where there were none before--only new absolute relocs
in RELRO sections for metadata, which are less problematic for
special linkage situations that take pains to avoid GOT generation.

Summary:
Cache the results from getMachineBasicBlocks in LexicalScopes to speed
up UserValueScopes::dominates queries. This replaces the caching done
in UserValueScopes. Compared to the old caching method, this reduces
memory traffic when a VarLoc is copied (e.g. when a VarLocMap grows),
and enables caching across basic blocks.
When compiling sqlite 3.5.7 (CTMark version), this patch reduces the
number of calls to getMachineBasicBlocks from 10,207 to 1,093. I also
measured a small compile-time reduction (~ 0.1% of total wall time, on
average, on my machine).
As a drive-by, I made the DebugLoc in UserValueScopes a const reference
to cut down on MetadataTracking traffic.
