[AArch64] Enable the select optimize pass for AArch64
This enabled the select optimize patch for ARM Out of order AArch64
cores. It is trying to solve a problem that is difficult for the
compiler to fix. The criteria for when a csel is better or worse than a
branch depends heavily on whether the branch is well predicted and the
amount of ILP in the loop (as well as other criteria like the core in
question and the relative performance of the branch predictor). The
pass seems to do a decent job though, with the inner loop heuristics
being well implemented and doing a better job than I had expected in
general, even without PGO information.
I've been doing quite a bit of benchmarking. The headline numbers are
these for SPEC2017 on a Neoverse N1:
500.perlbench_r -0.12%
502.gcc_r 0.02%
505.mcf_r 6.02%
520.omnetpp_r 0.32%
523.xalancbmk_r 0.20%
525.x264_r 0.02%
531.deepsjeng_r 0.00%
541.leela_r -0.09%
548.exchange2_r 0.00%
557.xz_r -0.20%
Running benchmarks with a combination of the llvm-test-suite plus
several versions of SPEC gave between a 0.2% and 0.4% geomean
improvement depending on the core/run. The instruction count went down
by 0.1% too, which is a good sign, but the results can be a little
noisy. Some issues from other benchmarks I had ran were improved in
rGca78b5601466f8515f5f958ef8e63d787d9d812e. In summary well predicted
branches will see in improvement, badly predicted branches may get
worse, and on average performance seems to be a little better overall.
This patch enables the pass for AArch64 under -O3 for cores that will
benefit for it. i.e. not in-order cores that do not fit into the "Assume
infinite resources that allow to fully exploit the available
instruction-level parallelism" cost model. It uses a subtarget feature
for specifying when the pass will be enabled, which I have enabled under
cpu=generic as the performance increases for out of order cores seems
larger than any decreases for inorder, which were minor.

a statement to be executed as if it were in a function body.
Clang's Parser does pretty well in disambiguating between declarations and
expressions. We have added DisambiguatingWithExpression flag which allows us to
preserve the existing and optimized behavior where needed and implement the
extra rules for disambiguating. Only few cases require additional attention:
* Constructors/destructors -- Parser::isConstructorDeclarator was used in to
disambiguate between ctor-looking declarations and statements on the global
scope(eg. `Ns::f()`).
* The template keyword -- the template keyword can appear in both declarations
and statements. This patch considers the template keyword to be a declaration
starter which breaks a few cases in incremental mode which will be tackled
later.
* The inline (and similar) keyword -- looking at the first token in many cases
allows us to classify what is a declaration.
* Other language keywords and specifiers -- ObjC/ObjC++/OpenCL/OpenMP rely on
pragmas or special tokens which will be handled in subsequent patches.
The patch conceptually models a "top-level" statement into a TopLevelStmtDecl.
The TopLevelStmtDecl is lowered into a void function with no arguments.
We attach this function to the global initializer list to execute the statement
blocks in the correct order.

[clang][modules] Serialize VFS overlay paths into PCMs
With implicitly built modules, the importing `CompilerInstance` assumes PCMs were built in a "compatible way" (i.e. with similarly set up instance). Either because their context hash matches, or because this instance has just built them.
There are some use-cases, however, where this assumption doesn't hold, libclang/c-index-test being one of them. There, the importing instance (or `ASTUnit`) is being set up while the PCM file is being deserialized. Until now, we've assumed the serialized paths to input files are the actual on-disk files, meaning the default physical VFS was always able to resolve them. This won't be the case after D135636. Therefore, this patch makes sure `ASTUnit` is initialized with the same VFS as the PCM it's deserializing - by storing paths to the VFS overlay files into the PCM itself.
For the VFS overlay files to be adopted at the very start of PCM deserialization, they are stored in a new section in the unhashed control block, together with header search paths and system header prefixes. The move to the unhashed control block should be safe: if two modules were built with different header search paths and they produced different results, the hashed part of the PCM file will reflect that.
