After D85099, if we have attribute group in the function signature that hasn't
been seen before, and later a callsite with the same attribute group, filecheck will evaluate
the first attribute group to for example '#0 {'. We now include { in the args_and_sig group to avoid this.

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.

Summary:
This introduces new flag to the update_test_checks and
update_cc_test_checks that allows for function attributes
to be checked in a check-line. If the flag is not set,
the behavior should remain the same.

This is effectively reverting rGbfdc2552664d to avoid test churn
while we figure out a better way forward.
We at least salvage the warning on name conflict from that patch
though.
If we change the default string again, we may want to mass update
tests at the same time. Alternatively, we could live with the poor
naming if we change -instnamer.
This also adds a test to LLVM as suggested in the post-commit
review. There's a clang test that is also affected. That seems
like a layering violation, but I have not looked at fixing that yet.

We now use the argparse Action objects to determine the name of the flags.
This fixes cases where the key for the stored result ('dest') is not the
same as the command line flag (e.g. --enable/--disable).
Also add a test that --disabled can be part of the initial UTC_ARGS.
This is split out from D78478

While D68850 allowed functions to be deleted I accidentally saved some
version of the function to be used once a suitable prefix was found.
This turned out to be problematic when the occasionally deleted function
is also occasionally modified. The test case is adjusted to resemble the
case in which the problem was found.

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.

When functions exist for some but not all run lines we need to be
careful when selecting the prefix. So far, a common prefix was
potentially chosen as there was never a "conflict" that would have
caused otherwise. With this patch we avoid common prefixes if they
are used by run lines that do not emit the function.

If we have `int foo(int a) { return a; }` and we run with --function-signature
enabled, we want a single variable declaration for `a` which is reused
later.

Attribute annotations on calls, e.g., #0, are not useful on their own.
This patch adds a flag to update_test_checks.py to scrub them.

Summary:
This commit adds basic tests for these update script to validate that
they still work as expected. In the future we could extend these tests
whenever new features are added to avoid introducing regressions.
