[OpenMP] Ensure testing for versions 4.5 and default - Part 1

Many OpenMP Clang tests do not RUN for version 4.5 and the default
version. This first patch in the series only handles test cases
which do not require any modifications in the CHECK lines after
adding RUN lines for default version.

[Parser] Suppress -Wempty-translation-unit if this is a header file

This is motivated by tooling (clangd, libclang etc) - headers without
declarations are legitimate even if they're not valid TUs.

The other use -x c-header cases (PCH/modules) are nonstandard anyway and this
warning doesn't seem necessary there either.

[SyntaxTree] Split tests for expressions

We do that because:
* Big tests generated big tree dumps that could hardly serve as documentation.
* In most cases the tests didn't share setup, thus there was not much addition in lines of code.

We split tests for:
* `UserDefinedLiteral`
* `NestedBinaryOperator`
* `UserDefinedBinaryOperator`
* `UserDefinedPrefixOperator`
* `QualifiedId`

[compiler-rt][asan][test] Skipt sanitizer_common tests on Sparc

When building on `sparc64-unknown-linux-gnu`, I found that a large number
of `SanitizerCommon-asan-sparc*-Linux` tests were `FAIL`ing, like

   SanitizerCommon-asan-sparc-Linux :: Linux/aligned_alloc-alignment.cpp
   SanitizerCommon-asan-sparcv9-Linux :: Linux/aligned_alloc-alignment.cpp

many of them due to

  fatal error: error in backend: Function "_Z14User_OnSIGSEGViP9siginfo_tPv": over-aligned dynamic alloca not supported.

which breaks ASan on Sparc.  Currently ASan is only built for the benefit
of `gcc` where it does work.  However, when enabling the compilation in
`compiler-rt` to make certain it continues to build, I missed
`compiler-rt/test/sanitizer_common` when disabling ASan testing on Sparc
(it's not yet enabled on Solaris).

This patch fixes the issue.

Tested on `sparcv9-sun-solaris2.11` with the `sanitizer_comon` testsuite enabled.

[test] XFAIL two tests with inlining debug info issues on Sparc

Currently only two test failures remain on Sparc, both
`sparcv9-sun-solaris2.11` and `sparc64-unknown-linux-gnu`:

  LLVM :: DebugInfo/Generic/debug-label-inline.ll
  LLVM :: Linker/subprogram-linkonce-weak.ll

They seem related in that debug info isn't generated for instruction
bundles (like `retl+add` in the delay slot).

I've filed separate bugs for both files (Bug 47129 and 47131), though it's
probably the same issue.

This patch `XFAIL`s the tests.

Tested on `sparcv9-sun-solaris2.11` and `amd64-pc-solaris2.11`.
