f230c29b40 Avoid performance penalty in sparc optimized memcpy/memset. 
fmovd clears the current exception field in the %fsr, fsrc2
does not and therefore runs more efficiently on some cpus.

	* sysdeps/sparc/sparc64/memcpy.S: Use fsrc2 to move 64-bit
	values between float registers.
	* sysdeps/sparc/sparc64/memset.S: Likewise.
	* sysdeps/sparc/sparc64/multiarch/memcpy-niagara2.S: Likewise.

fed806c3af tests: move -D_FORTIFY_SOURCE to CPPFLAGS 
The -D_FORTIFY_SOURCE flags are being added to the test-specific CFLAGS
values when they should be the test-specific CPPFLAGS values.  Otherwise
the values don't override the user-specified CPPFLAGS and might end up
breaking the tests.

9c6ea9facb Fix stack size and address inconsistency due to executable stack 
When a stack is marked executable due to loading a DSO that requires
an executable stack, the logic tends to leave out a portion of stack
after the first frame, thus causing a difference in the value returned
by pthread_getattr_np before and after the stack is marked
executable. It ought to be possible to fix this by marking the rest of
the stack as executable too, but in the interest of marking as less of
the stack as executable as possible, the path this fix takes is to
make pthread_getattr_np also look at the first frame as the underflow
end of the stack and compute size and stack top accordingly.

The above happens only for the main process stack. NPTL thread stacks
are not affected by this change.
