Add utility script to generate checks for opt or llc regression tests
This is an enhancement of the existing update_llc_test_checks.py script.
It adds some of the functionality from the script used in D17999 to make
the IR checking more flexible.
The bad news:
This actually is 'My First Python Program'. Thus, it's likely that I have
violated all best practices of Python programming if I've made a functional
change from the original program. If you see anything that's obviously
wrong, please let me know or feel free to fix it. I didn't even read any
documentation...
The good news:
I tested this on ~10 existing opt/llc regression tests, and it does what
I hoped for. It produces exact checking for IR regression tests and doesn't
signficantly change the existing llc-with-x86-target asm checking. The opt
tests that were modified in r263667, r263668, r263674, and r263679 are
examples of the expected results, except that this version of the script
puts the check lines ahead of the IR to follow the existing llc/asm
behavior.
If there are no complaints/fallout, we should be able to remove the
original script. Extending this script to be used for non-x86 and clang
regression tests would be the expected follow-up steps.

[asan] Intercept all Heap* related imports from ucrtbase.dll
ucrtbase.dll appears to be built with some kind of cross-module
inlining, because there are calls to imported Heap* routines sprinkled
throughout the code. This inlining defeats our attempts to hotpatch
malloc, _malloc_base, and related functions. Failing to intercept an
allocation or deallocation results in a crash when the program attempts
to deallocate or reallocate memory with the wrong allocator.
This change patches the IAT of ucrtbase.dll to replace the addresses of
the imported Heap* functions with implementations provided by ASan. We
don't globally intercept the win32 Heap* functions because they are
typically used by system DLLs that run before ASan initializes.
Eventually, we may want to intercept them, but for now I think this is
the minimal change that will keep ASan stable.

[clang-tidy] Add support for different char-types for the readability-redundant-string-cstr checker.
Summary:
The current checker is able to recognize std::string but does not recognize other string variants.
This patch is adding the support for any string defined with basic_string without considering the
the underlying char type.
The most common variant is: 'std::wstring' based on 'wchar_t'.
There are also other string variants added to the standard: u16string, u32string, etc...

[Hexagon] Generate PIC-specific versions of save/restore routines
In PIC mode, the registers R14, R15 and R28 are reserved for use by

also apply to save/restore functions, which do not follow the standard

[Statepoints] Fix yet another issue around gc pointer uniqueing
Given that StatepointLowering now uniques derived pointers before
putting them in the per-statepoint spill map, we may end up with missing

Fix this by keeping two maps, one mapping gc pointers to their
de-duplicated values, and one mapping a de-duplicated value to the slot

[debuginfo] Include dwo_name in the split unit to improve dwp diagnostics
When multiple DWP files are merged together and duplicate DWO IDs are
found it's currently difficult to give an actionable error message - the
DW_AT_name of the CU could be provided, but might be identical (if the
same source file is built into two different configurations), which
doesn't help the user identify the problem.
When no intermediate DWP files are generated, the path to the two DWO
files could be provided - but is lost once the DWOs are merged into a
DWP.
So, include the name of the DWO (dwo_name) in the split file so that
collissions involving a source CU from a DWP can be better diagnosed.
