[OpenMP] Improve mappable expressions Sema.
Summary:
This patch adds logic to save the components of mappable expressions in the clause that uses it, so that they don't have to be recomputed during codegen. Given that the mappable components are (will be) used in several clauses a new geneneric implementation `OMPMappableExprListClause` is used that extends the existing `OMPVarListClause`.
This patch does not add new tests. The goal is to preserve the existing functionality while storing more info in the clauses.

Use gcc's rules for parsing gcc-style response files
In gcc, \ escapes every character in response files. It is true that this makes
it harder to mention Windows files in rsp files, but not doing this means clang
disagrees with gcc, and also disagrees with the shell (on non-Windows) which
rsp file quoting is supposed to match. clang isn't free to choose what to do
here.
In general, the idea for response files is to take bits of your command line
and write them to a file unchanged, and have things work the same way. Since
the command line would've been interpreted by the shell, things in the rsp file
need to be subject to the same shell quoting rules.
People who want to put Windows-style paths in their response files either need
to do any of:
* escape their backslashes
* or use clang-cl which uses cl.exe/cmd.exe quoting rules
* pass --rsp-quoting=windows to clang to tell it to use
cl.exe/cmd.exe quoting rules for response files.

[LoopVectorize] Don't consider conditional-load dereferenceability for marked parallel loops

void Test(int *res, int *c, int *d, int *p) {
for (int i = 0; i < 16; i++)
res[i] = (p[i] == 0) ? res[i] : res[i] + d[i];
}
we did not vectorize the loop. Even with "assume_safety" the check that we
don't if-convert conditionally-executed loads (to protect against
data-dependent deferenceability) was not elided.
One subtlety: As implemented, it will still prefer to use a masked-load
instrinsic (given target support) over the speculated load. The choice here
seems architecture specific; the best option depends on how expensive the
masked load is compared to a regular load. Ideally, using the masked load still
reduces unnecessary memory traffic, and so should be preferred. If we'd rather
do it the other way, flipping the order of the checks is easy.
The LangRef is updated to make explicit that llvm.mem.parallel_loop_access also
implies that if conversion is okay.

This patch is what was the "instcombine" portion of D14185, with an additional

The patch causes instcombine to replace sequences of extractelement-insertvalue-store

driver: Add a `--rsp-quoting` flag to pick response file quoting.
Currently, clang-cl always uses Windows style for unquoting, and clang always
uses POSIX style for unquoting.
With this flag, it's possible to change these defaults.
In general, response file quoting should match the shell the response file is
used in. On Windows, it's possible to run clang-cl in a bash shell, or clang in
cmd.exe, so a flag for overriding the default behavior is natural there.
On non-Windows, Windows quoting probably never makes sense (except maybe in
Wine), but having clang-cl behave differently based on the host OS seems
strange too. So require that people who want to use posix-style response
files with clang-cl on non-Windows pass --rsp-quoting=posix.

Maintain register numbering across xml include features
Summary:
If the remote uses include features when communicating
xml register info back to lldb, the existing code would reset the
lldb register index at the beginning of each include node.
This would lead to multiple registers having the same lldb register index.
Since the lldb register numbers should be contiguous and unique,
maintain them accross the parsing of all of the xml feature nodes.

Re-apply r267206 with a fix for the encoding problem: when the immediate of

variant cannot encode it. Therefore, set the subreg part accordingly.
[AArch64] Fix optimizeCondBranch logic.
The opcode for the optimized branch does not depend on the size
of the activate bits in the AND masks, but the AND opcode itself.
Indeed, we need to use a X or W variant based on the AND variant
not based on whether the mask fits into the related variant.
Otherwise, we may end up using the W variant of the optimized branch
for 64-bit register inputs!
