Log Message:
-----------
Define OPpSELF_IN_PAD private flag to OP_METHSTART
This flag indicates that `$self` argument handling has already been
performed by the subroutine signature, so it should find the value
already in the pad.

Log Message:
-----------
Add a subsignature_append_fence_op()
A "fence op" is a miscellaneous op fragment that performs some work for
side-effects during processing of a subroutine signature. In terms of
timing, it will run at some time after any previously-defined arguments
have been assigned from argument values passed in by the caller, but
before any defaulting expressions for parameters that come after it are
run.
We specifically make no guarantees about whether parameters defined
after this op have had their values assigned, nor whether defaulting
expressions of earlier parameters have already been invoked. This is
intentional because upcoming changes will change the order of these.
The intention here is that method subroutines will use a fence op for
the `OP_METHSTART` behaviour, ensuring that subsequent defaulting
expressions can see the values of field bindings established by
processing the `$self` parameter.

Log Message:
-----------
Process `$self` in method subs as a subsignature parameter
This has at least three advantages:
* Removes more special-case code from `class.c` and makes generated
optrees more similar to others
* Ensures that no other ops appear in the optree before signature
handling (as the OP_METHSTART used to). This will be useful for
upcoming faster-signatures changes
* Corrects the previous "off-by-one" error in parameter counts as
reported by the argument count check exception messages
