04c83c34 - [NFCI] Extract out the addVariableConstraints CGASM Function (#175261)

[NFCI] Extract out the addVariableConstraints CGASM Function (#175261) This function is needed in identical form for CIR codegen, and pulling it out into AsmStmt is effectively trivial. The only thing that actually needs the codegen in it is the ability to diagnose, so this patch adds that as a callback. AsmStmt seems to be the most logical place for this to happen, as it does other similar things. Howver, unlike the other similar things, th is is the same between MS and GCC, so it doesn't need separate implementations.
