This reapplies the fix for PR13303 now with more justification. Based on my execution of the GDB 7.5 test suite this results in: expected passes: 16101 -> 20890 (+30%) unexpected failures: 4826 -> 637 (-77%) There are 23 checks that used to pass and now fail. They are all in gdb.reverse. Investigating a few looks like they were accidentally passing due to extra breakpoints being set by this bug. They're generally due to the difference in end location between gcc and clang, the test suite is trying to set breakpoints on the closing '}' that clang doesn't associate with any instructions. llvm-svn: 169304
