[PATCHv3,04/11] Replace M_PI2l with lit_pi_2_d in libm-test.inc

  This is useful in situations where the long double type is
less precise than the type under test.  This adds a new
wrapper macro LITM(x) to each type to append the proper
suffix onto macro constants found in math.h.

	* libm-test.inc: Replace usage of M_PI2l with
	(lit_pi_2_d): New macro.

	* math/test-double.h (LITM): New macro.
	* math/test-float.h (LITM): Likewise.
	* math/test-ldouble.h (LITM): Likewise.
