[ARM] __ARM_FP & __ARM_NEON_FP defined when -march=armv7-m

gcc/:

	* config/arm/arm.h (TARGET_NEON_FP): Removed conditional definition,
	define to zero if !TARGET_NEON.
	(TARGET_CPU_CPP_BUILTINS): Added second condition before defining
	__ARM_FP macro.

gcc/testsuite/:

	* gcc.target/arm/macro_defs0.c: New test.
	* gcc.target/arm/macro_defs1.c: New test.
	* gcc.target/arm/macro_defs2.c: New test.
