[NFC] computeSPIRKernelABIInfo(): use SPIRABInfo

[linjamaki]

Summary

Make computeSPIRKernelABIInfo() to use SPIRABIInfo instead of
DefaultABIInfo.

[Anastasia]

LGTM! Thanks.

Do you think we can test this somehow?

[linjamaki]

Thanks for the review.

In an upcoming HIPSPV patch there will be a test that depends on this change.

@Anastasia I used to have svn commit access, but haven't committed anything for a long while in LLVM, so don't know if I can get them back to github by just asking. So, can you please commit these HIPSPV patches for us?

@Anastasia - or do you think there's someone else more suitable for pushing these patches in for us? Thanks.
