Log:
[CodeGen] Hoist common AsmPrinter code out of X86, ARM, and AArch64
Every known PE COFF target emits /EXPORT: linker flags into a .drective
section. The AsmPrinter should handle this.
While we're at it, use global_values() and emit each export flag with
its own .ascii directive. This should make the .s file output more
readable.
