perldiag: Document ‘Can't call mro_method_changed_in()’
optree_constants.t: Correct line number in comment

Why we need a reference like this is beyond me, but it is extremely
fragile, because even cosmetic changes to gv.t will throw it off.
That said, at least the next person looking at it won’t be as puzzled
as I was (until the next gv.t change).
[perl #118305] make dtrace sub-entry probe support lexsubs

No tests, because I don’t know how to write them.

See also <https://rt.perl.org/rt3/Ticket/Display.html?id=118305#txn-1221543>.

I have tested this manually, so I know it works and no longer crashes.

Hopefully someone else can follow this up with tests.
Improved struct pmop alignment fix - avoid the slow path on 64 bit systems.

Commit c2a50ddb1bed6576 works round an alignment bug in the slab allocator
for 32 bit systems built with 64 bit IVs. However, the C pre-processor logic
meant that the test path was enabled on true 64 bit systems. It's not needed
there, so improve the logic so that it isn't compiled for platforms where
pointers are 64 bit.
release_managers_guide.pod: amended based on v5.19.1 experience
PATCH [perl #118563]: Fix perldata ident defn

The formal definition of identifiers was missing the fact that every
character in an identifier must match \w.  This also adds some
explanation.
Update perlsub.pod for lvalue subroutines.
Remove BmRARE and BmPREVIOUS

These were only used by the study code, which was disabled in 5.16.0
and removed shortly thereafter.
Increase $B::VERSION to 1.44
