- The root cause is that target constant materialization in X86 fast-isel
creates a PC-rel addressing which may overflow 32-bit range in non-Small code
model if .rodata section is allocated too far away from code segment in
MCJIT, which uses Large code model so far.
- Follow the similar logic to fix non-Small code model in fast-isel by skipping
non-Small code model.
