[PATCH, Darwin, x86, testsuite] Make match strings more specific.

[Iain Sandoe]

Some of the i386.exp tests fail on Darwin (and at least one passes
incorrectly on Linux) because their scan-asm match strings are too
general.  In some cases the strings also match instances in the .file
and size directives or in comment output.  This patch makes the match
strings more specific.

tested on x86_64-darwin and x86_64-linux (--target_board=unix\{-m32,-m64\}\{,-fpic\})
Note that it is expected for one fewer test passes on m32 Linux, since
the m64 test for ptwrite2.c had been erroneously passing there and that
is now corrected.

Applied as obvious to mainline,
Iain

	* gcc.target/i386/pconfig-1.c: Scan for the string in the generated
	code, not in comments or miscellaneous directives. Adjust expected
	count.
	* gcc.target/i386/pr18041-1.c: Likewise.
	* gcc.target/i386/pr18041-2.c: Likewise.
	* gcc.target/i386/wbinvd-1.c: Likewise.
	* gcc.target/i386/wbnoinvd-1.c: Likewise.
	* gcc.target/i386/pr66819-3.c: Specifically, check that there is no
	call to "bar".
	* gcc.target/i386/pr66819-4.c: Likewise.
	* gcc.target/i386/pr82662.c
	* gcc.target/i386/ptwrite2.c: Make the checks look for the specific
	destination register, don't try the m32 test on m64 targets.
