* optabs.h (enum optab_index): Add new OTI_logb and OTI_ilogb.
(logb_optab, ilogb_optab): Define corresponding macros.
* optabs.c (init_optabs): Initialize logb_optab and ilogb_optab.
* genopinit.c (optabs): Implement logb_optab and ilogb_optab
using logb?f2 and ilogb?i2 patterns.
* builtins.c (expand_builtin_mathfn): Handle BUILT_IN_LOGB{,F,L}
using logb_optab, and BUILT_IN_ILOGB{,F,L} using ilogb_optab.
(expand_builtin): Expand BUILT_IN_LOGB{,F,L} and BUILT_IN_ILOGB{,F,L}
using expand_builtin_mathfn if flag_unsafe_math_optimizations is set.
* reg-stack.c (subst_stack_regs_pat): Handle UNSPEC_XTRACT_FRACT
and UNSPEC_XTRACT_EXP.
* config/i386/i386.md (*fxtractdf3, *fxtractsf3, *fxtractxf3): New
patterns to implement fxtract x87 instruction.
(logbdf2, logbsf2, logbxf2, ilogbsi2): New expanders to implement
logb, logbf, logbl, ilogb, ilogbf and ilogbl built-ins as inline x87
intrinsics.
(UNSPEC_XTRACT_FRACT, UNSPEC_XTRACT_EXP): New unspecs to represent
x87's fxtract insn.
* gcc.dg/builtins-38.c: New test.
