builtins.def: Define new builtin functions exp...
* builtins.def: Define new builtin functions exp, expf, expl,
log, logf and logl (and their __builtin_* variants).
* optabs.h (enum optab_index): Add new OTI_exp and OTI_log.
Define exp_optab and log_optab.
* optabs.c (init_optans): Initialize exp_optab and log_optab.
* genopinit.c (optabs): Implement exp_optab and log_optab
using exp?f2 and log?f2 patterns.
* builtins.c (expand_builtin_mathfn): Handle BUILT_IN_EXP*
and BUILT_IN_LOG* using exp_optab and log_optab respectively.
(expand_builtin): Ignore the new builtins (and all cos and
sin variants) when not optimizing. Expand new builtins via
expand_builtin_mathfn when flag_unsafe_math_optimizations.
* doc/extend.texi: Document new exp and log builtins.
* doc/md.texi: Document new exp?f2 and log?f2 patterns
(and previously undocumented cos?f2 and sin?f2 patterns).
