Artem Belevich 0060fffc82 [CUDA] Bump default GPU architecture to sm_35. 
It's the oldest GPU architecture currently supported by all CUDA versions clang
can use.

Fangrui Song 8aa3f507c3 [Driver] Don't pass -plugin LLVMgold.so when the linker is ld.lld 
This is does not cover the case when ld is lld (e.g. /usr/bin/ld on
modern FreeBSD systems).

Fangrui Song 70e0935256 [Driver][test] Refactor LLVMgold tests 
LLVMgold.so tests are duplicated in several places. Deduplicate them.
Move the tests to lto.c and lto.cu
Specify -fuse-ld=bfd or -fuse-ld=gold.

In a future change, if -fuse-ld=lld or CLANG_DEFAULT_LINKER=lld without -fuse-ld=, we will remove -plugin /path/to/LLVMgold.so

Artem Belevich 4c86af7579 [CUDA] add REQUIRES fields for CUDA variants of LTO tests. 
Also relax checking for nvptx triple. This should avoid test failure if
the test is executed on 32-bit platform.

Artem Belevich ecb178bb35 [CUDA] Disable LTO for device-side compilations. 
This fixes host-side LTO during CUDA compilation. Before, LTO
pipeline construction was clashing with CUDA pipeline construction.

At the moment there's no point doing LTO on device side as each
device-side TU is a complete program.  We will need to figure out
compilation pipeline construction for the device-side LTO when we
have working support for multi-TU device-side CUDA compilation.
