Modify LLVMConfig to produce LLVM_USE_CRT variables in build-directory. It helps to set the same compiler debug options like in builded library.

Runtime function __kmpc_push_tripcount better to call inside of the task
context for target regions. Otherwise, the libomptarget is unable to
link the provided tripcount value for nowait target regions and
completely looses this information.

Summary:
This revision add the `access` and `ifBound` combinators to the Stencil library:
* `access` -- constructs an idiomatic expression for accessing a member (a
`MemberExpr`).
* `ifBound` -- chooses between two `StencilParts` based on the whether an id is
bound in the match (corresponds to the combinator of the same name in
RangeSelector).

The matchSelectPattern const wrapper is never explicitly called with the optional Instruction::CastOps argument, and it turns out that it wasn't being forwarded to matchSelectPattern anyway!
Noticed while investigating clang static analyzer warnings.

Static analyzer complains about const_cast uninitialized variables, we should explicitly set these to null.
Ideally that const wrapper would go away though.......

typeinfo names aren't symbols but string constant contents
stored in compiler-generated typeinfo objects, but llvm-cxxfilt
can demangle these for Itanium names.
In the MSVC ABI, these are just a '.' followed by a mangled
type -- this means they don't start with '?' like all MS-mangled
symbols do.

Summary:
Introduces facilities for easily building source-code strings, including
idiomatic use of parentheses and the address-of, dereference and member-access
operators (dot and arrow) and queries about need for parentheses.

These ifdefs contain code that isn't specific to MSVC but useful for
any windows target, like MinGW.

vsnprintf(NULL, 0, ...) works for measuring the needed string
size on all supported Windows variants; it's supported since
at least MSVC 2015 (and LLVM requires a newer version than that),
and works on both msvcrt.dll (since at least XP) and UCRT with MinGW.
The previous use of ifdefs was wrong as well, as __MINGW64__ only is
defined for 64 bit targets, and the define without trailing
underscores is never defined automatically (neither by clang nor
by gcc).

This fixes build warnings in MinGW mode.
Also remove leftover if (log) {} around the log macro.

The PECOFF object file plugin uses the dbghelp API, but doesn't
specify that it has to be linked in anywhere.
Current MSVC based builds have probably succeeded, as other parts
in LLDB have had a "#pragma comment(lib, "dbghelp.lib")", but there's
currently no such pragma in the PECOFF plugin.
The "#pragma comment(lib, ...)" approach doesn't work in MinGW mode
(unless the compiler is given the -fms-extensions option, and even
then, it's only supported by clang/lld, not by GCC/binutils), thus
add it to be linked via CMake. (The other parts of LLDB that use
dbghelp are within _MSC_VER ifdefs.)

llvm-readobj currently handles .stack_sizes.* (e.g. .stack_sizes.foo)
as a normal stack sizes section. Though MC does not produce sections with
such names. Also, linkers do not combine .stack_sizes.* into .stack_sizes.
A mini discussion about this correctness issue is here: https://reviews.llvm.org/D67757#inline-609274
This patch changes implementation so that only now only '.stack_sizes' name is
accepted as a real stack sizes section.

Enable flag introduced in rL294998. Security concerns are no longer valid, since function signatures for mentioned libc functions has no nonnull attribute (Clang does not generate them? I see no nonnull attr in LLVM IR for these functions) and since rL372091 we carefully annotate the callsites where we know that size is static, non zero. So let's enable this flag again..

Remove any predicate that we replace with a vctp intrinsic, and try
to remove their operands too. Also look into the exit block to see if
there's any duplicates of the predicates that we've replaced and
clone the vctp to be used there instead.

The fact that index==-1 means "no arguments" is not obvious and only
used in one place from what I can tell. Also fixes several warnings
about using the cursor index as if it was a size_t when comparing.
Not fully NFC as we now also correctly update the partial argument list
when injecting the fake empty argument in the CompletionRequest
constructor.

Try to generate ushll/sshll for aarch64_neon_ushl/aarch64_neon_sshl,
if their first operand is extended and the second operand is a constant
Also adds a few tests marked with FIXME, where we can further increase
codegen.
