Update the GSMATCH handling in vms/gen_shrfls.pl.

This code (which only runs if you have set PERLSHR_USE_GSMATCH in
the environment) has not been updated in a long time.  It was
assuming that $] had only five digits after the decimal, whereas
it's had six for some time. And it assumed that the Perl5 version
could be represented in 4 bits, which was true up through 5.15
but isn't true anymore.

So get all the digits of the version number, and go wild and spend
5 bits on the value of $Config{PERL_VERSION}, which will get us
through 5.31.  That only leaves three bits in which to encode all
the options that could break binary compatibility, whereas in fact
we need about thirty bits.

So clearly this only works in a situation where the configuration
can be standardized and/or different configurations are packaged
separately.

Fix ExtUtils::Constant test failure on VMS.

Awaiting upstream application for many months now at:

  https://rt.cpan.org/Public/Bug/Display.html?id=81249

But it's not at all clear that this module is even maintained as
the only two "maintainers" are former pumpkings who probably had
to become maintainers in order to cut a Perl release.

From the message originally submitted upstream:

It turns out the easiest and most robust way to handle the fact that
filename case may or may not be preserved is simply to do all
filename comparisons in a case blind fashion.  This is safe to do
because there is no practical possibility of distinct filenames that
differ only by case, especially with the short list of well-known
files being considered here.
toke.c: Under -DT, report pending idents more clearly

These are treated as forced tokens of type 'p'.  Indicate what the 'p'
means in the debug output.

This:

### 0:LEX_NORMAL/XSTATE "\n;"
### forced token:
### <== 'p'

becomes this:

### 0:LEX_NORMAL/XSTATE "\n;"
### forced token:
### <== 'p' (pending identifier)
Correct three sub call comments in perly.y

NOAMP is only emitted by toke.c when there are no parentheses.  If
there is a parenthesis following a word, the lexer conjures up an '&'
token from nowhere.
