[Patch, i386]: Commited: Rewrite and macroize sin, cos and sincos x87 patterns

[Uros Bizjak]

Hello!

This patch rewrites and macroizes sin, cos and sincos x87 patterns. It
rewrites these patterns the same way as fsqrt patterns have been
rewritten (inherent float extensions of DFmode and SFmode operands to
XFmode).

Patch was bootstrapped on i686-pc-linux-gnu and x86_64-pc-linux-gnu, 
regression tested on both targets for c, c++ and fortran. Patch is 
commited to mainline as revision 120620.

         * config/i386/i386.md (*sinxf2): Rename to *sinxf2_i387.
         (*cosxf2): Rename to cosxf2_i387.

         (*sindf2, *sinsf2): Extend operand 1 to XFmode.  Macroize patterns
         using X87MODEF12 mode macro. Rename patterns to
         *sin_extend<mode>xf2_i387.  Use SSE_FLOAT_MODE_P to disable 
patterns
         for SSE math.
         (*cosdf2, *cossf2): Ditto.
         (sincosdf3, sincossf3): Ditto.  Rewrite corresponding 
splitters 	        to match extended input operands.

         (sincos<mode>3): New expander.

         (*sinextendsfdf2, *cosextendsfdf2, *sincosextendsfdf3): Remove
         insn patterns and corresponding splitters.

Uros.
