Fix the remaining TCL-style quotes found in the testsuite. This is another mechanical change accomplished though the power of terrible Perl scripts. I have manually switched some "s to 's to make escaping simpler. While I started this to fix tests that aren't run in all configurations, the massive number of tests is due to a really frustrating fragility of our testing infrastructure: things like 'grep -v', 'not grep', and 'expected failures' can mask broken tests all too easily. Essentially, I'm deeply disturbed that I can change the testsuite so radically without causing any change in results for most platforms. =/ llvm-svn: 159547 2012-07-03 03:09:46 +08:00			`; RUN: opt < %s -instcombine -S \| not grep "sub i32 0"`
