Re: [PATCH]: PR29335 use MPFR for builtin sincos

For a call like sincos(0.0,s,c), where "s" and "c" are pointers, I
transform this into e.g. "(void)(*s=0.0,*c=1.0)".

Bootstrapped on sparc-sun-solaris2.10, no regressions.  The new testcases
all pass.  In the transcendental accuracy testsuite, there is no sincos
test, however I was able to shoehorn the values used in the sin and cos
tests through builtin sincos and they all get "perfect" results.

Okay for mainline?

This might transform a valid gimple statement into a non-gimple one - did you verify that the various places that might fold the statement correctly handle this case?

Richard.
