This mainly transitions the LLVM intrinsic string table from character emission to string literal emission, which I confirmed happens for me locally. I moved the guts of StringToOffsetTable to a cpp file so I could move the `EmitLongStrLiterals` cl::opt global to a non-vague linkage home in the `TableGen` library. I had to add missing FormatVariadic.h includes to account for moving other includes to a cpp file.
