* vm_insnhelper.c (INLINE): define as `inline` when it is optimized.
define as `static inline` when it is not optimized to keep
the symbol generated.
* vm_insnhelper.c (vm_getivar): use `INLINE` to force inline
so that a compiler inlines it into vm_getinstancevariable
and optimizes out is_attr and related branches.
* vm_insnhelper.c (vm_getivar): use `inline` to recommend inline.
Without this vm1_ivar_set is degraded.
benchmark results:
minimum results in each 5 measurements.
