[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.
