clang-cl passes -x86-asm-syntax=intel to the cc1 invocation so that assembly listings produced by the /FA flag are printed in Intel dialect. That flag however should not affect the *parsing* of inline assembly in the program. (See r322652) When compiling normally, AsmPrinter::emitInlineAsm is used for assembling and defaults to At&t dialect. However, when compiling for ThinLTO, the code which parses module level inline asm to find symbols for the symbol table was failing to set the dialect. This patch fixes that. (See the bug for more details.) Differential revision: https://reviews.llvm.org/D82862
