Summary:
Lack of that support has taken me by surprise.
I need to add (or at least look at) some tests for https://reviews.llvm.org/D47980#1127615,
and i don't really fancy doing that by hand.
The asm pattern is quite similar to that of x86:

just with `#` replaced with `;`

This patch replaces the --x86_extra_scrub command line argument to automatically support a second level of regex-scrubbing if it improves the matching of nearly-identical code patterns. The argument '--extra_scrub' is there now to force extra matching if required.
This is mostly useful to help us share 32-bit/64-bit x86 vector tests which only differs by retl/retq instructions, but any scrubber can now technically support this, meaning test checks don't have to be needlessly obfuscated.
I've updated some of the existing checks that had been manually run with --x86_extra_scrub, to demonstrate the extra "ret{{[l|q]}}" scrub now only happens when useful, and re-run the sse42-intrinsics file to show extra matches - most sse/avx intrinsics files should be able to now share 32/64 checks.
Tested with the opt/analysis scripts as well which share common code - AFAICT the other update scripts use their own versions.

If we don't mark the cfi line as optional, the script won't
work with 'nounwind' code. Without that attr, there may be
extra noise in the asm body that we don't want to see.

The script allows the auto-generation of checks for cost model tests to speed up their creation and help improve coverage, which will help a lot with PR36550.
If the need arises we can add support for other analyze passes as well, but the cost models was the one I needed to get done - at the moment it just warns that any other analysis mode is unsupported.
I've regenerated a couple of x86 test files to show the effect.

fact use regular expression syntax to use regular expressions.
Should restore the bots. Sorry for the noise on this test.
Thanks to Philip for spotting the bug!

do explicit scrubbing of the offsets of stack spills and reloads.
You can always turn this off in order to test specific stack slot usage.
We were already hiding most of this, but the new logic hides it more
generically. Notably, we should effectively hide stack slot churn in
functions that have a frame pointer now, and should also hide it when
changing a function from stack pointer to frame pointer. That transition
already changes enough to be clearly noticed in the test case diff,
showing *every* spill and reload is really noisy without benefit. See
the test case I ran this on as a classic example.

Summary:
I noticed that clang will emit variables such as %indirect-arg-temp when
running update_cc1_test_checks.py and therefore update_cc1_test_checks.py
wasn't adding FileCheck captures for those variables.

Some of the update_*_test_checks regexes have been moved into a
library, so we might as well use them in update_mir_test_checks.
Also includes minor bugfixes to the regexes that are there so we
don't regress update_mir_test_checks

Summary:
This revision refactors 1. parser 2. CHECK line adder of utils/update_{,llc_}test_checks.py
