  Log Message:
  -----------
  [LoongArch] Reimplement to prevent Pseudo{CALL, LA*}_LARGE instruction reordering (#100099)

The Pseudo{CALL, LA*}_LARGE instruction patterns specified in psABI
v2.30 cannot be reordered. This patch sets scheduling boundaries for
these instructions to prevent reordering. The Pseudo{CALL, LA*}_LARGE
instruction is moved back to Pre-RA expansion, which will help with
subsequent address calculation optimizations.
