-Wrange-loop-analysis is a subgroup of -Wloop-analysis and will warn when
a range-based for-loop makes copies of the elements in the range. If possible,
suggest the proper type to prevent copies, or the non-reference to help
distinguish copy versus non-copy forms. Existing warnings in -Wloop-analysis
are moved to -Wfor-loop-analysis, also a subgroup of -Wloop-analysis.

LLVM can now detect if a fd is seekable on windows.
Original commit message:
Actually check if lseek works instead of using a filename based heuristic.

Stop using `DIDescriptor`'s wrapper around
`MDNode::replaceAllUsesWith()` (which is going away). The new home for
this logic is `DIBuilder::replaceTemporary()`, added in LLVM r234695.

This just adds a front end option to let the back end know the target has PPC
direct move instructions.

Previously, many error messages would simply be "read-only variable is not
assignable" This change provides more information about why the variable is
not assignable, as well as note to where the const is located.

Follow-up to r234666. With this, the -m[no-]global-merge options
have the expected behavior. Previously, -mglobal-merge was ignored,
and there was no way of enabling the optimization.

Summary:
tools::arm::getARMFloatABI() was falling back to guessing soft-float because
it wasn't seeing the GNUEABIHF environment from ComputeEffectivClangTriple
when it was called from gnutools::Assemble::ConstructJob.
Fix by using the effective clang triple in gnutools::Assemble, which now
matches the -triple flag used by cc1 and ClangAs jobs.

More fallout from r228234; when looking up an identifier in a PCH that
imports the Cocoa module on Darwin, it was taking 2 to 5 seconds
because we were hammering the MapVector::erase() function, which is
O(n). For now, just clear() the contained SmallVector to get back to
0.25 - 0.5 seconds. This is probably not the long-term fix, because
without modules or without PCH the performance is more like 0.02
seconds.

Take advantage of the delayed typo no longer being eagerly corrected to
a keyword to filter out keyword corrections (and other things like
unresolved & overloaded expressions, which have placeholder types) when
correcting typos inside of a decltype().

Even though these symbols are in a comdat group, the Microsoft linker
really wants them to have internal linkage.
I'm planning to tweak the mangling in a follow-up change. This is a
straight revert with a 1-line fix.

The placement of the 'delete' call that was removed in the unique_ptr
migration in r234597 was not an accident. The raw_ostream has to be
destroyed before you do the rename on Windows, otherwise you get
ERROR_ACCESS_DENIED. We can still use unique_ptr, we just need to do a
manual reset().
Also, range-for-loop-ify this code.

Now that TailRecursionElimination has been fixed with r222354, the
threshold on size for lifetime marker insertion can be removed. This
only affects named temporary though, as the patch for unnamed temporaries
is still in progress.
My previous commit (r222993) was not handling debuginfo correctly, but
this could only be seen with some asan tests. Basically, lifetime markers
are just instrumentation for the compiler's usage and should not affect
debug information; however, the cleanup infrastructure was assuming it
contained only destructors, i.e. actual code to be executed, and was
setting the breakpoint for the end of the function to the closing '}', and
not the return statement, in order to show some destructors have been
called when leaving the function. This is wrong when the cleanups are only
lifetime markers, and this is now fixed.

Given something like 'int({}, 1)', we would try to emit a diagnostic
regarding the excess element in the scalar initializer. However, we
assumed that the initializer list had an element in it.
