builtin-apply2.c: Skip test on arm hardfloat ABI targets.

2013-10-17  Charles Bayis  <charles.baylis@linaro.org>

	* gcc.dg/builtin-apply2.c: Skip test on arm hardfloat ABI targets.
	* gcc.dg/tls/pr42894.c: Remove dg-options for arm*-*-* targets.
	* gcc.target/arm/thumb-ltu.c: Remove dg-skip-if and require
	effective target arm_thumb1_ok.
	* lib/target-supports.exp
	(check_effective_target_arm_fp16_ok_nocache): Don't force
	-mfloat-abi=soft when building for hardfloat target.
