[PATCH]: MPC cleanup in testsuite

["Kaveh R. GHAZI" <ghazi at caip dot rutgers dot edu>]

This patch removes gunk from the testsuite that was necessary only
while MPC was optional.  It depends on this patch to require MPC:
http://gcc.gnu.org/ml/gcc-patches/2009-11/msg00731.html

Tested on x86_64-unknown-linux-gnu, no regressions.

Okay for mainline once the above patch goes in?

		Thanks,
		--Kaveh

	* gcc.dg/torture/builtin-math-6.c: Assume we have MPC.
	* gcc.dg/torture/builtin-math-7.c: Likewise.
	* gfortran.dg/complex_intrinsic_7.f90: Likewise.
	* gfortran.dg/complex_intrinsic_8.f90: Likewise.
	* gfortran.dg/integer_exponentiation_4.f90: Re-enable some tests.
	* lib/target-supports.exp (check_effective_target_mpc,
	check_effective_target_mpc_pow, check_effective_target_mpc_arc):
	Delete.
