YJIT: Fix unexpected truncation when outputing VALUE
Previously, YJIT incorrectly discarded the upper 32 bits of the object pointer when writing out VALUEs to setup default keyword arguments.
In addition to incorrectly truncating, the output pointers were not properly tracked for handling GC compaction moving the referenced objects.
YJIT previously attempted to encode a mov instruction with a memory destination and a 64 bit immediate when there is no such encoding possible in the ISA. Add an assert to mitigate not being able to catch this at build time.
