Re-add filtering options with fixes for failed tests. We were not passing the
is_filtered argument in all check generator calls in update_cc_test_checks.py
Enhance the various update_*_test_checks.py tools to allow filtering the tool
output with regular expressions. The --filter option will emit only tool output
lines matching the given regular expression while the --filter-out option will
emit only tools output lines not matching the given regular expression. Filters
are applied in order of appearance on the command line (or in UTC_ARGS) and the
first matching filter terminates the search.
This allows test authors to create more focused tests by removing irrelevant
tool output and checking only the pieces of output necessary to test the desired
functionality.

When checking if two prefixes can be merged for a function,
update_llc_test_checks.py removed IR comments before comparing
llc outputs of different RUN lines.
This means, if one RUN line emited lines starting with ';' and another
RUN line emited the same lines except the ones starting with ';', both
RUNs would be merged (if they share a prefix).
However, CHECK-NEXT lines check the comments, otherwise they fail, so
the script should not merge RUNs if they contain different comments.

Now that FileCheck eagerly complains when prefixes are unused,
the update script does the same, and is becoming very common
to need to drop some prefixes, yet figuring out the file
it complains about isn't obvious unless it actually tells us.
This has been rather useful in our downstream CHERI target where we want
to run tests both with addrspace(0) and addrspace(200) pointers.
With this patch we can prefix the opt command with
`sed -e 's/addrspace(200)/addrspace(0)/g' -e 's/-A200-P200-G200//g'` to
test both cases using the same IR input.

This allows to check for various globals (metadata/attributes/...) and

This allows us to have shared logic over multiple test runs, e.g. do we
have unused prefixes, or which function bodies have conflicting outputs
for a prefix appearing in different RUN lines.
This patch is just wrapping existing functionality, and replacing its uses.
A subsequent patch would then fold the current functionality into the newly
introduced class.

Add the --include-generated-funcs option to update_cc_test_checks.py so that any
functions created by the compiler that don't exist in the source will also be
checked.
We need to maintain the output order of generated function checks so that
CHECK-LABEL works properly. To do so, maintain a list of functions output for
each prefix in the order they are output. Use this list to output checks for
generated functions in the proper order.

With this patch we will match most *uses* of "temporary" named things in
the IR via regular expressions, not their name at creation time. The new
"values" we match are:
- "unnamed" globals: `@[0-9]+`
- debug metadata: `!dbg ![0-9]+`
- loop metadata: `!loop ![0-9]+`
- tbaa metadata: `!tbaa ![0-9]+`
- range metadata: `!range ![0-9]+`
- generic metadata: `metadata ![0-9]+`
- attributes groups: `#[0-9]`
We still don't match the declarations but that can be done later. This
patch can introduce churn when existing check lines contain the old
hardcoded versions of the above "values". We can add a flag to opt-out,
or opt-in, if necessary.

Remove the local versions of the IR_FUNCTION_RE matcher (they weren't doing anything different), and ensure all the function name matchers accept '.' and '-'.
We don't need to use '\.' inside python regex sets either, or '\-' as long as thats at the end of the set.
Update test scripts were limited because they performed a single action
on the entire file and if that action was controlled by arguments, like
the one introduced in D68819, there was no record of it.
This patch introduces the capability of changing the arguments passed to
the script "on-the-fly" while processing a test file. In addition, an
"on/off" switch was added so that processing can be disabled for parts
of the file where the content is simply copied. The last extension is a
record of the invocation arguments in the auto generated NOTE. These
arguments are also picked up in a subsequent invocation, allowing
updates with special options enabled without user interaction.
To change the arguments the string `UTC_ARGS:` has to be present in a
line, followed by "additional command line arguments". That is
everything that follows `UTC_ARGS:` will be added to a growing list
of "command line arguments" which is reparsed after every update.

With D69701, the options used when running the script on a file will be
recorded and reused on a rerun. This allows us to hide new features
behind flags, starting with the "define" that was introduced in D68819.

This adds a switch to the update_test_checks that triggers arguments and
other function annotations, e.g., personality, to be present in the
check line. If not set, the behavior should be the same as before.
If arguments are recorded, their names are scrubbed from the IR to allow
merging.

Summary:
Prior to this change, phi nodes were never considered defs, and so we ended up with undefined variables for any loop. Now, instead of trying to find just defs, we iterate over each actual IR value in the line, and replace them one by one with either a definition or a use.
We also don't try to match anything in the comment portions of the line.
I've tested it even on things like function pointer calls, etc, and against existing test cases uses update_test_checks
With this change, we are able to use update_tests on the cyclic cases in newgvn.
The only case i'm aware of that will misfire is if you have a string with which contains a valid token.
However, this is the same as it is now, with a slightly larger set of strings that may misfire.
Prior to this change, a test with the string " %a =" would be replaced.
