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

Improve the return slot optimization to be both more aggressive (not limited to sret parameters), and safer (when the passed pointer might be invalid). Thanks to Duncan and Chris for the idea behind this, and extra thanks to Duncan for helping me work out the trap-safety. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48280 91177308-0d34-0410-b5e6-96231b3b80d8

Fix an issue where GVN was performing the return slot optimization when it was not safe. This is fixed by more aggressively checking that the return slot is not used elsewhere in the function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47544 91177308-0d34-0410-b5e6-96231b3b80d8

rip out a ton of intrinsic modernization logic from AutoUpgrade.cpp, which is for pre-2.9 bitcode files. We keep x86 unaligned loads, movnt, crc32, and the target indep prefetch change. As usual, updating the testsuite is a PITA. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133337 91177308-0d34-0410-b5e6-96231b3b80d8
