A bunch of tests had broken yet undetected syntax errors
in their assembly output regexps. Things like mismatched quotes,
using ^ instead of - for negation, etc.
In addition, since CL 716060 using commas as separators between
regexps doesn't work, and ends up just silently dropping every
regexp after the comma.
Fix all these things, and add a test to make sure that we're not
silently dropping regexps on the floor.
After this CL I will do some cleanup to align with CL 716060, like
replacing commas and \s with spaces (which was the point of that CL,
but wasn't consistently rewritten everywhere).

It currently isn't because it does load/store/load/store/...
Rework to do overwrite processing in pairs so it is instead
load/load/store/store/...

We can't coalesce a non-WB store with a subsequent Move, as the
result of the store might be the source of the move.
There's a simple codegen test. Not sure how we might do a real test,
as all the repro's I've come up with are very expensive and unreliable.
Fixes #71228

We don't need noLimit checks in a bunch of places.
Also simplify folding of provable constant results.
At this point in the CL stack, compilebench reports no performance
changes. The only thing of note is that binaries got a bit smaller.

This lets us combine more write barriers, getting rid of some of the
test+branch and gcWriteBarrier* calls.
With the new write barriers, it's easy to add a few non-pointer writes
to the set of values written.
We allow up to 2 non-pointer writes between pointer writes. This is enough
for, for example, adjacent slice fields.
