bc080221b3 [Clang] Fix Offloading related tests after D156363
This patch fixes failing tests after checking the return code from the
driver. This is mostly due to the ROCm libraries not being present
during most compilations. Passing `-nogpuinc` should allow us to compile
without it for tests that require it. Additionally, some old tests set
the architecture of Nvidia tests to `sm_35` which is officially
unsupported in CUDA 12+ so it prints an error. We just increase in this
case.

f39c399d9d [Driver] -###: exit with code 1 if hasErrorOccurred
The exit code for -### is inconsistent. Unrecognized options lead to
exit code 1, as expected. However, most others errors (including invalid
option value) lead to exit code 0, differing from GCC and most utilities.

This is a longstanding quirk of -###, and we didn't fix it because many
driver tests need adjustment.

Change -### to be similar to -fdriver-only -v and exit with code 1.

This requires fixing many driver tests, but the end result gives us
stronger tests.

* Existing `RUN: %clang -### ...` tests usually don't use `CHECK-NOT: error:` or `--implicit-check-not=error:`.
  If a change introduces an error, such a change usually cannot be detected.
* Many folks contributing new tests don't know `-fdriver-only -v`.
  To test no driver error/warning for new tests, they can use the familiar `-### -Werror`
  instead of `-fdriver-only -v -Werror`.

An incomplete list of prerequisite test improvement:

* 2f79bb10461d114783a1548201928549ace09755: add -nogpulib to some AMDGPU tests
* 9155e517e6e1cda474d0d0fa82f71696c325bc10: add --cuda-path= (test w/ and w/o /usr/local/cuda)
* 80765ede5bbcca1364c2d4ae06127011eaba6389: -mcpu=native may return either 0 or 1, depending on whether `--target=` specifies a native target
* abae53f43f0d1da8d8e421f4a628d7ec64d6e365: fix -fuse-ld=lld misuses (test w/o and w/o /usr/local/bin/ld.lld)
* ab68df505e5bb8808ee44f53044b50ca7575098e: add -resource-dir= and -fvisibility=hidden
 to some -fsanitize=cfi tests
* d5ca1602f64114f612ad5630f04e4aa90591c78d: --rtlib=platform without --unwindlib= may fail if CLANG_DEFAULT_UNWINDLIB=unwindlib

This reverts commit 8c3550b1a78fde7bf28f420da8447d9fde37017f.

clang/test/Driver/fsanitize.c has a mysterious failure worth

63fbc77121 [Driver][test] Remove unused/obsoleted REQUIRES: clang-driver
It (introduced by 556d713c70bfaf58ac18d089883f9c34c581633a) appears to be
related to the removed dragonegg project. In addition, the feature was a bit
misnamed and may lur users to unnecessarily use it.

ed181efa17 [HIP][AMDGPU] expand printf when compiling HIP to AMDGPU
Summary:
This change implements the expansion in two parts:
- Add a utility function emitAMDGPUPrintfCall() in LLVM.
- Invoke the above function from Clang CodeGen, when processing a HIP
  program for the AMDGPU target.

The printf expansion has undefined behaviour if the format string is
not a compile-time constant. As a sufficient condition, the HIP
ToolChain now emits -Werror=format-nonliteral.
