Prepare run-time method calling mechanism for cross-compilation
The current way of encoding the offsetof() of the method_ members in
QV4::Runtime is not portable when cross-compiling from a 64-bit host
(where the offsetof would be calculated on) to a 32-bit target (where
the offset would be different), or vice versa. In preparation for making
this work, this patch first replaces the direct use of the run-time
members with use through a void * and an enum for indexing. This gives
us some type-safety in some places and will also allow for a translation
of the pointer offset from host pointer indexing to target pointer
indexes.
As a bonus we can avoid going through the engine->runtime indirection in
the interpreter altogether and call the static methods right away.
