* Merge of the reuse-temps branch:xleroy2010-09-021-17/+101
| | | | | | | | | | | | - Reload temporaries are marked as destroyed (set to Vundef) across operations in the semantics of LTL, LTLin, Linear and Mach, allowing Asmgen to reuse them. - Added IA32 port. - Cleaned up float conversions and axiomatization of floats. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1499 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e

CminorSel to Asm: added Sbuiltin/Ibuiltin instruction. PrintAsm: adapted expansion of builtins. C2Clight: adapted detection of builtins.
