c-family: implement -ffp-contract=on
Implement -ffp-contract=on for C and C++ without changing default
behavior (=off for -std=cNN, =fast for C++ and -std=gnuNN).
gcc/c-family/ChangeLog:
* c-gimplify.cc (fma_supported_p): New helper.
(c_gimplify_expr) [PLUS_EXPR, MINUS_EXPR]: Implement FMA
contraction.
gcc/ChangeLog:
* common.opt (fp_contract_mode) [on]: Remove fallback.
* config/sh/sh.md (*fmasf4): Correct flag_fp_contract_mode test.
* doc/invoke.texi (-ffp-contract): Update.
* trans-mem.cc (diagnose_tm_1): Skip internal function calls.
