Support for inlined built-ins.
AST: add ef_inline flag to external functions.
Selection: recognize calls to inlined built-ins and inline them as Sbuiltin.
CminorSel to Asm: added Sbuiltin/Ibuiltin instruction.
PrintAsm: adapted expansion of builtins.
C2Clight: adapted detection of builtins.
Conventions: refactored in a machine-independent part (backend/Conventions)
and a machine-dependent part (ARCH/SYS/Conventions1).
