Add more tests of various libm functions.

This patch adds more tests of various libm functions found through
random test generation to give increased ulps on 32-bit x86.

Tested for x86_64 and x86.

	* math/auto-libm-test-in: Add more tests of acosh, asin, asinh,
	atanh, cabs, carg, cbrt, cosh, csqrt, erf, erfc, exp, exp10,
	expm1, hypot, log, log10, log1p, log2, pow, sinh, tan and tgamma.
	* math/auto-libm-test-out: Regenerated.
	* sysdeps/i386/fpu/libm-test-ulps: Update.
	* sysdeps/x86_64/fpu/libm-test-ulps: Likewise.
