Support -masm= flag for x86 assembly targets. For assembly files without .intel_syntax or .att_syntax directives, allow the -masm= flag to supply a default assembly dialect. For example, C:\TMP> type intel.s .text mov al,0 C:\TMP> clang -masm=intel -c intel.s Without this patch, one would need to pass an "-mllvm -x86-asm-syntax=" flag directly to the backend. C:\TMP> clang -mllvm --x86-asm-syntax=intel -c intel.s Differentials Review: http://reviews.llvm.org/D22285 llvm-svn: 275877
