Previously it used llvm-readobj -s, now changed to llvm-objdump -section-headers,
that reduced the output significantly and helps to read/support it.

Our implementation supported integer value previously.
ld can use expression,
for example, it is OK to write
. = SEGMENT_START("foobar", .);
Patch implements that.

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
<<<<<INVALID SOURCE LOCATION>>>>>

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.

This reduces the number of copies and reg_sequences
when using fp constant vectors. This significantly
reduces the code size in local-stack-alloc-bug.ll

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.

It was possible situation about some commands just were not processed
(were skipped) because of a bug appeared when constraint checking used.
Testcase is attached.

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).

The ValueSymbolTable is used to detect name conflict and rename
instructions automatically. This is not needed when the value
names are automatically discarded by the LLVMContext.
No functional change intended, just saving a little bit of memory.
This is a recommit of r281806 after fixing the accessor to return
a pointer instead of a reference and updating all the call-sites.

Where possible, remove the const char* version. To keep the
risk and impact here minimal, I've only done the simplest
functions.
In the process, I found a few opportunities for adding some
unit tests, so I added those as well.
Tested on Windows, Linux, and OSX.

This refactors the cstring literal creation as mentioned in the couple of FIXMEs
littered in the various invocations to CreateMetadataVar. This centralises the
definition of the literals, and will enable changing the literal creation to a
single site. NFC.

* recurse through intermediate LabelStmts and AttributedStmts when checking
whether a statement inside a switch declares a variable
* if the end of a compound statement is reachable from the chosen case label,
and the compound statement contains a variable declaration, it's not valid
to just emit the contents of the compound statement -- we must emit the
statement itself or we lose the scope (and thus end lifetimes at the wrong
point)

This supports creating symlinks to tools in different directories than
the tool is built to. This is useful for the LLDB framework build which
I’m sending patches for shortly.

These clean up some unnecessary or instructions in
cases with complex loops.
In the original testcase I noticed this, the same
or with exec was repeated 5 or 6 times in a row. With
this only one is emitted or sometimes a copy.
