[HIP] Remove disabled irif library

[ashi1]

Summary

Device Libraries has removed irif.amdgcn.bc, so we need to remove this requirement from HIP Toolchains. Also a few header functions need to be updated. Since fence was previously included in irif, we need to move them into hip.amdgcn.bc instead.

If you don't mind, can you please do another revision with full context (-U99999), makes it easier to review and makes it less likely that svn patch screws up.

this seems to be duplicate of https://reviews.llvm.org/D51857

Is HIP github ready for this change?

[ashi1]

Added diff with full context. Also, I need to find replacements for few functions in HIP github before this can be submitted.

[ashi1]

I've added a hip.amdgcn.bc library for the fence functions that were originally in irif library.

[ashi1]

The device libraries has been updated, and the hip.amdgcn.bc library is now available there.

maybe we should put hip.amdgcn.bc at the beginning. In the future, it may depend on other bc's.

[ashi1]

I've moved the hip.amdgcn.bc to the top of the libs. Updated test as well.

LGTM. Thanks!
