Add function_abi.{h,cc}
This patch adds new structures and functions for handling
multiple ABIs in a translation unit. The structures are:
- predefined_function_abi: describes a static, predefined ABI
- function_abi: describes either a predefined ABI or a local
variant of one (e.g. taking -fipa-ra into account)
The patch adds functions for getting the ABI from a given type
or decl; a later patch will also add a function for getting the
ABI of the target of a call insn.
Although ABIs are about much more than call-clobber/saved choices,
I wanted to keep the name general in case we add more ABI-related
information in future.
