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.
