New Revision: 39861
URL: https://trac.parrot.org/parrot/changeset/39861

Log:
[NCI] Made generated function build_call_func() attempt to use NCI to build
call frames (if the built Parrot supports that) rather than installing NCI
functions for every potential NCI signature when first loaded.  This reduces
startup time by 8.03% and reduces the number of PMCs generated on startup
dramatically.

The behavior is unchanged on builds which do not support JIT, though they may
be slightly faster as well.
