Remove miscellaneous GCC >= 4.7 version conditionals.
This patch removes miscellaneous __GNUC_PREREQ (4, 7) conditionals
that are now dead.

Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch).

	* sysdeps/arm/atomic-machine.h
	[__GNUC_PREREQ (4, 7) && __GCC_HAVE_SYNC_COMPARE_AND_SWAP_4]:
	Change conditional to [__GCC_HAVE_SYNC_COMPARE_AND_SWAP_4].
	[__GCC_HAVE_SYNC_COMPARE_AND_SWAP_4 && !__GNUC_PREREQ (4, 7)]:
	Remove conditional code.
	[!__GNUC_PREREQ (4, 7) || !__GCC_HAVE_SYNC_COMPARE_AND_SWAP_4]:
	Change conditional to [!__GCC_HAVE_SYNC_COMPARE_AND_SWAP_4].
	* sysdeps/i386/sysdep.h [__ASSEMBLER__ && __GNUC_PREREQ (4, 7)]:
	Change conditional to [__ASSEMBLER__].
	[__ASSEMBLER__ && !__GNUC_PREREQ (4, 7)]: Remove conditional code.
	[!__ASSEMBLER__ && __GNUC_PREREQ (4, 7)]: Change conditional to
	[!__ASSEMBLER__].
	[!__ASSEMBLER__ && !__GNUC_PREREQ (4, 7)]: Remove conditional
	code.
	* sysdeps/unix/sysv/linux/sh/atomic-machine.h (rNOSP): Remove
	conditional macro definitions.
	(__arch_compare_and_exchange_val_8_acq): Use "u" instead of rNOSP.
	(__arch_compare_and_exchange_val_16_acq): Likewise.
	(__arch_compare_and_exchange_val_32_acq): Likewise.
	(atomic_exchange_and_add): Likewise.
	(atomic_add): Likewise.
	(atomic_add_negative): Likewise.
	(atomic_add_zero): Likewise.
	(atomic_bit_set): Likewise.
	(atomic_bit_test_set): Likewise.
	* sysdeps/x86_64/atomic-machine.h [__GNUC_PREREQ (4, 7)]: Make
	code unconditional.
	[!__GNUC_PREREQ (4, 7)]: Remove conditional code.
