Change condition for determining whether a function is small for inlining metrics so that very long functions

Add a size alignment check to the .seh_stackalloc directive parser. Add a
more descriptive error message to the .seh_handler directive parser.

Add methods to the TargetAsmInfo struct in support of all this.

- Works only if ABI is o32.
- Zero-sized structures cannot be passed.
- There is a lot of redundancy in generated code.
