Full Unicode 9.0 and Emoji 4.0 text segmentation support.
Faster normalization, string indexing, and string concatenation.
Collation improvements, including support for reversing any of the levels.
Optional output buffering on file handles.
Numerous tweaks to dynamic optimization and JIT compilation to improve code
quality, with a focus on Perl 6 I/O code.

Log message:
Bump PKGREVISION for perl-5.24.0 for everything mentioning perl.

Log message:
Import MoarVM-2016.03 from wip.

Short for "Metamodel On A Runtime", MoarVM is a virtual machine built
especially for Rakudo Perl 6 and the NQP Compiler Toolchain. The primary
backend target for the Christmas 2015 release of Perl 6, MoarVM stands
out amongst the various Rakudo and NQP compilation targets by:

- Running the Perl 6 specification test suite in the least time
- Passing more of the Perl 6 specification tests than Rakudo Perl 6 on
  other backends
- Having the lowest memory usage
- Having the best startup time
- Being fastest to build both NQP and Rakudo - and thus your Perl 6 and
  NQP programs too!
- Being the only backend to support strings at grapheme level
