Use asm style type names and improve asm typer.

Use asm style type names and improve asm typer.

The current typing-asm mishandles the relationship between
unsigned numbers and int. Restructuring and using type shortcuts
that approximate asm types.

lgtm other than some cleanup. In general, should we introduce union types where
there are conjunctive conditions?

type->Is(cache_.kAsmUnsigned) ||
Maybe we need to have a type that represents the union of these four types?
