Assorted x86 testsuite fixes.

I think HJ has already fixed the binutils and ld tests with his
2013-09-27 readelf change, but this allows them to pass with wider
address output as per Nick's 2013-09-12 readelf change.

binutils/testsuite/
	* binutils-all/x86-64/compressed-1a.d: Allow wide display of addresses.
gas/testsuite/
	* gas/cfi/cfi-x86_64.d: Match when lacking end of section padding.
ld/testsuite/
	* ld-pe/cfi.d: Allow wide display of addresses.
