Unfortunately systemtap's dtrace emulation doesn't support -xnolibs so

When generating an object file with "dtrace -G", dtrace also modifies
the input object files.

This causes two problems:

1) Since the objects are modified, their modification times are updated
which may break dependency checks by make.

2) on FreeBSD at least, once the object has been processed it can't be
processed again by dtrace -G

the compiler was generating probes even for unused inline functions.

The default compiler on FreeBSD 11 however doesn't generate probes for
these unused inline functions, and dtrace -G fails because it can't

APItest/t/handy.t: Skip locale tests when not in locale

In XS code, the macros that pay attention to locale don't check if they
are being called from within the scope of 'use locale'; they assume that
the code calling them wouldn't be doing so unless appropriate.  That's
not true of Perl-level code.  I forgot that when writing these tests.
Normally it doesn't show up as a problem as the underlying locale is the
C locale, which on almost all platforms has the effect of not being in a
locale.  But the VMS C locale is special, and so doesn't meet the
assumptions of these tests.  The solution is to skip locale-aware macros
unless we are testing locale.

Some code points < 256 are the same whether represented in UTF-8, or

parsing a string, using UTF-8 is avoided unless necessary, because of
the extra overhead required for processing UTF-8.  This means that when,
during the parse, we discover we need to convert to UTF-8, we have to,
in effect, reparse whatever we have so far to make sure those code
points that differ under UTF-8 get their proper representation.  This
reparsing would not be necessary if we know that the string doesn't have
such code points.

It turns out that keeping track of having seen UTF-8 variant code points
is cheap, requiring no extra branch instructions.  And the payoff is

Handle chop(@a =~ tr///)

RT #130198

'chop(@x =~ tr/1/1/)' crashed with an assertion failure. Ditto for chomp.

There are two quirks which together cause this. First, the op tree for
a tr// is different from other bind ops:

    $ perl -MO=Concise -e'$x =~ m/a/'
    5  <@> leave[1 ref] vKP/REFC ->(end)
    1     <0> enter ->2
    2     <;> nextstate(main 1 -e:1) v:{ ->3
    4     </> match(/"a"/) vKS ->5
    -        <1> ex-rv2sv sK/1 ->4
    3           <#> gvsv[*x] s ->4

    $ perl -MO=Concise -e'$x =~ tr/a/b/'
    5  <@> leave[1 ref] vKP/REFC ->(end)
    1     <0> enter ->2
    2     <;> nextstate(main 1 -e:1) v:{ ->3
    -     <1> null vKS/2 ->5
    -        <1> ex-rv2sv sKRM/1 ->4
    3           <#> gvsv[*x] s ->4
    4        <"> trans sS ->5

Note that the argument for the match is a child of the match, while the
arg of the trans is an (earlier) sibing of the trans (linked by a common
null parent).

The normal code path that croaks when e.g. a match is seen in an lvalue

    $ perl -e'chop(@a =~ /a/)'
    Can't modify pattern match (m//) in chop at -e line 1, near "/a/)

is skipped, since lvalue() is only called for the first child of a null op.

Fixing this is as simple as calling lvalue() on the RHS too if the RHS is
a trans op.

The second issue is that chop and chomp are special-cased not to flatten
an array; so

    @b = 10..99;
    chop $a, @b, $c;

pushes 3 items on the stack to pass to pp_chop, rather than 102. pp_chop()
itself then iterates over any array args.

The compiler was seeing the rv2av op in chop(@a =~ tr///) and was setting
the OPf_REF (don't flatten) flag on it. Which then caused pp_trans to
panic when its arg was an AV rather than a string.

This second issue is now moot, since after the fix suggested above, we
will have croaked before we reach the place where OPf_REF would be set.

This commit adds lots of tests, since tr/a/a/ and tr/a/b/r are
special-cased in terms of whether they are regarded as modifying the
var they are bound to.

tests will be run simultaneously.)

We can submit patches for modules with serial-only test suites, but for now
at least, the best course of action seems to be for sync-with-cpan to run

The original goal of this sequence of patches was to address RT#130375. That
ticket proposes extending the release manager's guide with discussion of
what regen/ does, and why it might sometimes be needed, and
thus why Porting/sync-with-cpan might yield a porting-test failure when
t/porting/regen.t detects that it needs to be run.

However, I find the RMG is already relatively bulky, and therefore hard to
navigate; so adding more text to it would exacerbate that problem. In
addition, it seems much better to merely fix this problem: we can always run
regen/, and if it makes any changes, those changes can be
committed along with the updated CPAN module being imported.

This merge also contains a few other improvements to Porting/sync-with-cpan:

- The log file it generates is now listed in .gitignore

- It allows specifying the module name with "-" rather than "::" as a name

- A bug that prevented the new module's tests from being run is now fixed

- The MANIFEST is now rewritten to accommodate any file deletions introduced
  by the updated CPAN module

- The messages emitted have been reworked slightly for clarity; in
  particular, "Fixing MANIFEST" will no longer be followed by a confusing
  and scary "'MANIFEST' is NOT sorted properly" message

- It now takes a --jobs option, which if supplied is used both for executing
  make and running the module's tests

- The --tarball option now works when the tarball isn't in the current

- It runs a few additional preflight checks that detect mistakes I found
  myself making

These changes have been tested by using Porting/sync-with-cpan to import
Test::Simple into blead as of 54f6f377a29af7d60918c003fc2c462439c340bd,
since that was the triggering case for RT#130375.
