In 32 bits, the first parameter is the pointer size, so it is different
for 32 and 64 bits. Add an additional check prefix with the pointer size
and match for both pointer sizes. Works in both 32 and 64 bits targets.
When an original module name is specified via @_originalDefinedIn attribute, we need to
use the original module name for all related runtime symbol names instead of the current
module names.
