* Create a direct lookup hash for ->isa() lookup, by retaining theNicholas Clark2008-09-121-0/+1
| | | | | | | | | | | de-duping hash used by S_mro_get_linear_isa_dfs(). Provide a new function Perl_get_isa_hash() to lazily retrieve this. (Which could actually be static if S_isa_lookup() and Perl_sv_derived_from() moved into mro.c.) Make S_isa_lookup() use this lookup hash in place of a linear walk of the linear isa. This should turn isa lookups from O(n) to O(1), which should make heavy users of ->isa() faster. (eg PPI, and hence Perl Critic). p4raw-id: //depot/perl@34354

However, key conversion replaces the original key with the converted key, so we need to ensure that conversion happens exactly once, else for a non-idempotent key conversion routine (eg ROT13) we will see double conversion in this case. p4raw-id: //depot/perl@31898
