Changed paths:
M ext/mro/mro.pm
M ext/mro/mro.xs
Log Message:
-----------
S_mro_get_linear_isa_c3() now uses sv_inc_nomg().
Previously it was coding the increment "longhand", to avoid bugs in 5.6.x.
However, this XS code is now exclusively in the core, and 5.6.x is long
dead, so there's no need to work around it.
The "longhand" code might *seem* to be more efficient (due to inlining some
logic) but it still required at least one call to a function in sv.c
(so no real change in generated code size) and that call was for the
increment 0 => 1, so likely called a lot, so no significant change in total
calls made.

Log Message:
-----------
Hash::Util::FieldHash fix_trigger can pre-size the hash before use.
This is only called by CLONE (and hence only matters for ithreads), but it's
an improvement, and small and self-contained.

Log Message:
-----------
Pre-size the %ENV hash before populating it from environ.
Also use HvTOTALKEYS() instead of HvKEYS(), as the latter makes a check for
placeholders, which here cannot make a difference.

Log Message:
-----------
Use sv_inc() for the env de-dup hash in S_init_postdump_symbols().
This replaces an hv_exists/hv_store pair with a single LVALUE hv_fetch.

Changed paths:

Log Message:
-----------
Pre-extend new anonymous hashes before assigning to them.
We know how many pairs of keys/values are on the stack, so pre-extend the
hash to the appropriate size, instead of letting the hash needlessly
re-size one or more times during the assignment loop.
