Add @llvm.dbg.value entries for the phi node created by -mem2reg
When phi nodes are created in the -mem2reg phase, the @llvm.dbg.declare
entries are converted to @llvm.dbg.value entries at the place where the
store instructions existed. However no entry is created to describe
the resulting value of the phi node.
The effect of this is especially noticeable in for loops which have a
constant for the intial value; the loop control variable's location
would be described as the intial constant value in the loop body once
the -mem2reg optimization phase was run.
This change adds the creation of the @llvm.dbg.value entries to describe
variables whose location is the result of a phi node created in -mem2reg.
Also when the phi node is finally lowered to a machine instruction it
is important that the lowered "load" instruction is placed before the
associated DEBUG_VALUE entry describing the value loaded.

[clang-rename] Fix handling of unchanged files
Fix the output of clang-rename for the files without modifications.
Update the code in clang-reorder-fields/tool/ClangReorderFields.cpp
to avoid inconsistency.
Example:
a.h:
struct A {};
a.cpp:
#include "a.h"
int main() { return 0; }
Before the changes the output looks like this:
clang-rename -qualified-name=A -new-name=B a.cpp

AMDGPU: Fix broken FrameIndex handling
We were trying to avoid using a FrameIndex operand in non-pointer
operands in a convoluted way, and would break because of
using TargetFrameIndex. The TargetFrameIndex should only be used
in the case where it makes sense to fold it as part of the addressing
mode, otherwise it requires materialization like a normal constant.
This wasn't working reliably and failed in the added testcase, hitting
the assert when processing the frame index.
The TargetFrameIndex was coming from trying to produce an AssertZext
limiting the maximum stack size. I'm not sure this was correct to begin
with, because it is apparently possible to have a single workitem
dispatch that requires all 4G of private memory.

When replacements have the same offset, make replacements with smaller length order first in the set.
Summary:
No behavioral change intended. The change makes iterating the replacements set more intuitive in Replacements class implementation. Previously, insertion is ordered before an deletion/replacement with the same offset, which is counter-intuitive for implementation, especially for a followup patch to support adding insertions around replacements.
With the current ordering, we only need to make `applyAllReplacements` iterate the replacements set reversely when applying them so that deletion/replacement is still applied before insertion with the same offset.

[compiler-rt] Disable building of profiling runtime when LLVM_USE_SANITIZER is set
Currently, when doing a ASanified build of LLVM (with Clang, compiler-rt and libcxx) via -DLLVM_USE_SANITIZER=Address and not using any other options, we already disable building of sanitizer runtimes (because they themselves can’t be sanitized) and also exclude the sanitizer tests. However, the same is not done for the profiling runtime, which will build fine, but then all the tests fail due to linking errors. Let’s disable the profiling runtime as well (when LLVM_USE_SANITIZER is set).
