Currently `immintrin.h` includes `pconfigintrin.h` and `sgxintrin.h` which contain inline assembly. It causes failures when building with the flag `-fno-gnu-inline-asm`. Fix by excluding functions with inline assembly when this extension is disabled. So far there was no need to support `_pconfig_u32`, `_enclu_u32`, `_encls_u32`, `_enclv_u32` on platforms that require `-fno-gnu-inline-asm`. But if developers start using these functions, they'll have compile-time undeclared identifier errors which is preferrable to runtime errors. rdar://problem/49540880 Reviewers: craig.topper, GBuella, rnk, echristo Reviewed By: rnk Subscribers: jkorous, dexonsmith, cfe-commits Differential Revision: https://reviews.llvm.org/D61621 llvm-svn: 360630
