x86: Strip whitespace in check_VecOperations

Browse Source 
Since the addition of pseudo prefixes changed how the scrubber treats
'{', we need to explicitly strip whitespace in check_VecOperations ().

	* config/tc-i386.c (check_VecOperations): Strip whitespace.
	* testsuite/gas/i386/optimize-1.s: Add whitespaces before
	{%k7} and {z},
	* testsuite/gas/i386/x86-64-optimize-2.s: Likewise.
