[BZ #2749]
* soft-fp/op-common.h (FP_TRUNC): When truncating a NaN, clear 
workbits in semi-raw fraction.
	* math/test-misc.c: Add new tests.

	* math/basic-test.c: Include test-skeleton.c.
	(TEST_TRUNC): Define.
	(truncdfsf_test, trunctfsf_test, trunctfdf_test): New.
	(main): Rename to ...
	(do_test): ...this.  Run new tests.
	(TEST_FUNCTION): Define.

	[BZ #2749]
	* soft-fp/op-4.h (__FP_FRAC_SUB_3, __FP_FRAC_SUB_4): Correct borrow
	handling for high words.
	* soft-fp/op-common.h (_FP_OVERFLOW_SEMIRAW): Always set inexact
	and overflow for infinity.
