Try to optimize takedispatcher to cleardispatcher.

The latter is cheaper and simpler code. In many of the simple ops,
we do not make any kind of call, and thus could never call one of
the defering things (nextsame, etc.)
Fix typo; timotimo++.
strip # from description in todo tests
bump nqp/moar rev for nativecallcast op
Make CURL::File faster

This gets us back the time we lost in the spectest recently.  Part of the
speedup is attained by only going through the directory of the CompUnitRepo
only once: this behaviour may need tweaking in certain situations.
CUR.files should call CURx.files, not .candidates
Fix signature of WHAT and VAR.
p6bindsig should not prevent immediate inlining

While on MoarVM we can lower signatures and thus optimize this out,
on other backends we don't, but should not lose the immediate inline
optimization on those. FROGGS++ also tracked down a behavior change
that resulted from disabling this optimization on r-p; it should not
make a difference, but this does indeed fix the r-p breakage.
ChangeLog entry
Ensure lowered_param names are unique.

Not just unique per block, but per file; it seems the optimizer is
now smart enough to flatten/inline and thus cause collisions.
Don't inline if/while pointy blocks.

This should unbreak htmlify.p6 from p6doc, fixing a bug reported by
Mouq++.
Also allow :from<NQP>
Only allow :from<Perl5 Perl6 NQP>
Allow for :from<JVM>
fix lookup of potential comp unit candidates

In case we have already seen a basename of a candidate we dropped
additional candidates. Therefor we missed a precompiled cu when we
already had seen a source file. Since the content of a directory
is not ordered the result depended on the phase of the moon, mostly.
Only lookup / once
[Temporal] accept colon in the timezone offset

This is valid in ISO 8601

http://www.w3.org/TR/NOTE-datetime
https://en.wikipedia.org/wiki/ISO_8601#Times
[Temporal] accept timezone offsets with only hours

specifying the minutes is optional
eg. 2014-07-09T01:50:05+12 is a valid ISO 8601 timestamp
Merge pull request #285 from carbin/nom

[Temporal] accept colon in the timezone offset
Add :no-precomp flag

This should allow for searches for a non-precompiled version of a module.
