Fix PR1850 by removing an unsafe transformation from VMCore/ConstantFold.cpp. Reimplement the xform in Analysis/ConstantFolding.cpp where we can use targetdata to validate that it is safe. While I'm in there, fix some const correctness issues and generalize the interface to the "operand folder". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44817 91177308-0d34-0410-b5e6-96231b3b80d8 2007-12-10 22:53:04 +00:00			`target datalayout = "e-p:32:32:32-i1:8:8-i8:8:8-i16:16:16-i32:32:32-i64:32:64-f32:32:32-f64:32:64-v64:64:64-v128:128:128-a0:0:64-f80:32:32"`

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. =/ git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159547 91177308-0d34-0410-b5e6-96231b3b80d8 2012-07-02 19:09:46 +00:00			`; RUN: opt < %s -instcombine -S \| not grep "ret i1 0"`
