ELF: Re-implement -u directly and remove CanKeepUndefined flag.
The semantics of the -u flag are to load the lazy symbol named by the flag. We
were previously relying on this behavior falling out of symbol resolution
against a synthetic undefined symbol, but that didn't quite give us the
correct behavior, so we needed a flag to mark symbols created with -u so
we could treat them specially in the writer. However, it's simpler and less
error prone to implement the required behavior directly and remove the flag.
This fixes an issue where symbols loaded with -u would receive hidden
visibility even when the definition in an object file had wider visibility.

[CodeGenPrepare] use branch weight metadata to decide if a select should be turned into a branch
This is part of solving PR27344:
https://llvm.org/bugs/show_bug.cgi?id=27344
CGP should undo the SimplifyCFG transform for the same reason that earlier patches have used this
same mechanism: it's possible that passes between SimplifyCFG and CGP may be able to optimize the
IR further with a select in place.
For the TLI hook default, >99% taken or not taken is chosen as the default threshold for a highly
predictable branch. Even the most limited HW branch predictors will be correct on this branch almost
all the time, so even a massive mispredict penalty perf loss would be overcome by the win from all
the times the branch was predicted correctly.
As a follow-up, we could make the default target hook less conservative by using the SchedMachineModel's
MispredictPenalty. Or we could just let targets override the default by implementing the hook with that
and other target-specific options. Note that trying to statically determine mispredict rates for
close-to-balanced profile weight data is generally impossible if the HW is sufficiently advanced. Ie,
50/50 taken/not-taken might still be 100% predictable.
Finally, note that this patch as-is will not solve PR27344 because the current __builtin_unpredictable()
branch weight default values are 4 and 64. A proposal to change that is in D19435.

The checker was noisy when running over llvm code base.
This patch is impriving the way string-compare functions are matched.
1) By default, do not report !strcmp(...) unless it's activate by the user,
2) Only match suspicious expression over a subset of expression (binary operator),
3) Added matching of macro wrapper used with clang on linux.
See bug: 27465.

[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.
Fixes PR27464.

Summary:
For folds (e.g. std::accumulate), check matches between the provided init value and the range's value_type. A typical error is "std::accumulate(begin, end, 0);", where begin and end have float value_type. See the documentation for more examples.
For now we check std::accumulate, std::reduce and std::inner_product.
