Daniel Sanders e94fb01a45 [mips][ias] Prevent double-filling of delay slots by generating '.set noreorder' regions.
Summary:
When clang is given -save-temps or -via-file-asm, any inline assembly in
the source is parsed twice. Once by the compiler, and again by the
assembler. We must take care to ensure that this doesn't lead to
double-filling delay slots.
