Add regular expressions to and DWARF Call Frame Information tests in case the architecture specific target is not compiled into LLVM.

[clayborg]

Summary

This should fix any build bots that avoid compiling some architectures into llvm after https://reviews.llvm.org/D88767.

This basically removes the testing for the original patch, since all of these tests would now pass even if the feature is completely reverted. Fortunately, I think the fix for that is easy. We don't need to add the regex to tests that already presuppose that the relevant llvm target is available. By the looks of things, that's everything except test/DebugInfo/dwarfdump-debug-frame-simple.test.

This test already requires the RISCV target -- see lit.local.cfg.

This test already requires the X86 target -- see lit.local.cfg. (Also, the llvm-mc cmd would not work without that target.)

llvm/test/MC/Mips/eh-frame.s

(On Diff #296576)

This test requires the mips target -- regex unnecessary.

This test requires the x86 target -- regex unnecessary.

Removed test cases that were only run if the architecture specific target is available.

good catch. I have update the patch!
