Use -mlink-builtin-bitcode instead of llvm-link to link
device library so that device library bitcode and user
device code can be compiled in a consistent way.
This is the same approach used by CUDA and OpenMP.

No longer use irif amdgcn library, instead we will use the previous fence functions from new hip.amdgcn.bc bitcode library. Update hip-device-libs.hip test as well.
llvm-svn: 344281
Summary:
HIP should link the bitcodes with caller functions before callee functions. Also added lit test to check the ordering of the linked bitcodes is matches.

Summary:
Use oclc_daz_opt_on.amdgcn.bc bitcode when option fcuda-flush-denormal-to-zero is enabled, otherwise use oclc_daz_opt_off.amdgcn.bc bitcode. Added lit tests to verify that the correct bitcode is linked when -fcuda-flush-denormal-to-zero option is enabled or disabled.
