Mark functions in some tests as 'nounwind'. Generating EH info for these functions causes the tests to fail for random reasons (e.g. looking for 'or' or counting lines with asm-printer; labels count as lines.) llvm-svn: 49003

add a cl::opt override for TargetLoweringBase's JumpIsExpensive This patch is not intended to change existing codegen behavior for any target. It just exposes the JumpIsExpensive setting on the command-line to allow for easier testing and emergency overrides. Also, change the existing regression test to use FileCheck, explicitly specify the jump-is-expensive option, and use more precise checks.
