[dsymutil] Introduce a new CachedBinaryHolder
The original binary holder has an optimization where it caches a static
library (archive) between consecutive calls to GetObjects. However, the
actual memory buffer wasn't cached between calls.
This made sense when dsymutil was processing objects one after each
other, but when processing them in parallel, several binaries have to be
in memory at the same time. For this reason, every link context
contained a binary holder.
Having one binary holder per context is problematic, because the same
static archive was cached for every object file. Luckily, when the file
is mmap'ed, this was only costing us virtual memory.
This patch introduces a new BinaryHolder variant that is fully cached,
for all the object files it load, as well as the static archives. This
way, we don't have to give up on this optimization of bypassing the
file system.

[clang-format/ObjC] Fix NS_SWIFT_NAME(foo(bar:baz:)) after ObjC method decl
Summary:
In D44638, I partially fixed `NS_SWIFT_NAME(foo(bar:baz:))`-style
annotations on C functions, but didn't add a test for Objective-C
method declarations.
For ObjC method declarations which are annotated with `NS_SWIFT_NAME(...)`,
we currently fail to annotate the final component of the selector
name as `TT_SelectorName`.
Because the token type is left unknown, clang-format will happily
cause a compilation error when it changes the following:
```
@interface Foo
- (void)doStuffWithFoo:(id)name
bar:(id)bar
baz:(id)baz
NS_SWIFT_NAME(doStuff(withFoo:bar:baz:));
@end
```
to:
```
@interface Foo
- (void)doStuffWithFoo:(id)name
bar:(id)bar
baz:(id)baz
NS_SWIFT_NAME(doStuff(withFoo:bar:baz
:));
@end
```
(note the linebreak before the final `:`).
The logic which decides whether or not to annotate the token before a
`:` with `TT_SelectorName` is pretty fragile, and has to handle some
pretty odd cases like pair-parameters:
```
[I drawRectOn:surface ofSize:aa:bbb atOrigin:cc:dd];
```
So, to minimize the effect of this change, I decided to only annotate
unknown identifiers before a `:` as `TT_SelectorName` for Objective-C
declaration lines.
Test Plan: New tests included. Confirmed tests failed before change and
passed after change. Ran tests with:

[ARM][AArch64] Armv8.4-A Enablement
Initial patch adding assembly support for Armv8.4-A.
Besides adding v8.4 as a supported architecture to the usual places, this also
adds target features for the different crypto algorithms. Armv8.4-A introduced
new crypto algorithms, made them optional, and allows different combinations:
- none of the v8.4 crypto functions are supported, which is independent of the
implementation of the Armv8.0 SHA1 and SHA2 instructions.
- the v8.4 SHA512 and SHA3 support is implemented, in this case the Armv8.0
SHA1 and SHA2 instructions must also be implemented.
- the v8.4 SM3 and SM4 support is implemented, which is independent of the
implementation of the Armv8.0 SHA1 and SHA2 instructions.
- all of the v8.4 crypto functions are supported, in this case the Armv8.0 SHA1
and SHA2 instructions must also be implemented.
The v8.4 crypto instructions are added to AArch64 only, and not AArch32,
and are made optional extensions to Armv8.2-A.
The user-facing Clang options will map on these new target features, their
naming will be compatible with GCC and added in follow-up patches.

SCEVExpander::expandAddRecExprLiterally(): check before casting as Instruction
Summary:
An alternative to D48597.
Fixes [[ https://bugs.llvm.org/show_bug.cgi?id=37936 | PR37936 ]].
The problem is as follows:
1. `indvars` marks `%dec` as `NUW`.
2. `loop-instsimplify` runs `instsimplify`, which constant-folds `%dec` to -1 (D47908)
3. `loop-reduce` tries to do some further modification, but crashes
with an type assertion in cast, because `%dec` is no longer an `Instruction`,
If the runline is split into two, i.e. you first run `-indvars -loop-instsimplify`,
store that into a file, and then run `-loop-reduce`, there is no crash.
So it looks like the problem is due to `-loop-instsimplify` not discarding SCEV.
But in this case we can just not crash if it's not an `Instruction`.
This is just a local fix, unlike D48597, so there may very well be other problems.
