Extended inline asm: revised treatment of clobbered registers.
- Treat clobbered registers as being destroyed by EF_inline_asm builtins
(which is the truth, semantically).
- To enable the above, represent clobbers as Coq strings rather than idents
and move register_by_name from Machregsaux.ml to Machregs.v.
- Side benefit: more efficient implementation of Machregsaux.name_of_register.
