fix unnamed fiefield issue and add tests for __builtin_preserve_access_index intrinsic

Authored by yonghong-song on Jul 11 2019, 2:14 PM.



This is a followup patch for
Handle unnamed bitfield properly and add more test cases

Fixed the unnamed bitfield issue. The unnamed bitfield is ignored
by debug info, so we need to ignore such a struct/union member
when we try to get the member index in the debug info.

D61809 contains two test cases but not enough as it does
not checking generated IRs in the fine grain level, and also
it does not have semantics checking tests.
This patch added unit tests for both code gen and semantics checking for
the new intrinsic.
