[BZ #6411]

[BZ #6411]
* sysdeps/powerpc/fpu/Makefile: Added test case tst-setcontext-fpscr.
* sysdeps/powerpc/fpu/feholdexcpt.c (_FPU_MASK_ALL): Define to replace
magic numbers.
* sysdeps/powerpc/fpu/fenv_libc.h (fesetenv_register): Dynamically
choose mtfsf insn based on PPC_FEATURE_HAS_DFP.
(relax_fenv_state): Same as above.
(FPSCR_29): Reserve bit in ISA 2.05.
(FPSCR_NI): Provide define for compat.
* sysdeps/powerpc/fpu/fesetenv.c (_FPU_MASK_ALL): Define to replace
magic numbers.
* sysdeps/powerpc/fpu/feupdateenv.c (_FPU_MASK_ALL): Define to replace
magic numbers.
* sysdeps/powerpc/fpu/tst-setcontext-fpscr.c: New file. Test case to
test setcontext and swapcontext with dynamic 64-bit FPSCR detection.
* sysdeps/powerpc/powerpc32/fpu/__longjmp-common.S (__longjmp): Adjust
access to hwcap to account for hwcap size increase to uint64_t.
* sysdeps/powerpc/powerpc32/fpu/setjmp-common.S (__sigsetjmp ):
Likewise.
* sysdeps/unix/sysv/linux/powerpc/powerpc32/getcontext-common.S
(*setcontext): Likewise.
* sysdeps/unix/sysv/linux/powerpc/powerpc32/power6/fpu/setcontext.S:
New file.
* sysdeps/unix/sysv/linux/powerpc/powerpc32/power6/fpu/swapcontext.S:
New file.
* sysdeps/unix/sysv/linux/powerpc/powerpc32/setcontext-common.S
(*setcontext): dynamically select mtfsf insn based on
PPC_FEATURE_HAS_DFP. Adjust access to hwcap to account for hwcap size
increase to uint64_t.
* sysdeps/unix/sysv/linux/powerpc/powerpc32/swapcontext-common.S
(*swapcontext): dynamically select mtfsf insn based on
PPC_FEATURE_HAS_DFP. Adjust access to hwcap to account for hwcap size
increase to uint64_t.
* sysdeps/unix/sysv/linux/powerpc/powerpc64/power6/fpu/setcontext.S:
New file.
* sysdeps/unix/sysv/linux/powerpc/powerpc64/power6/fpu/swapcontext.S:
New file.
* sysdeps/unix/sysv/linux/powerpc/powerpc64/setcontext.S
(*setcontext): dynamically select mtfsf insn based on
PPC_FEATURE_HAS_DFP.
* sysdeps/unix/sysv/linux/powerpc/powerpc64/swapcontext.S
(*swapcontext): dynamically select mtfsf insn based on
PPC_FEATURE_HAS_DFP.
