  Log Message:
  -----------
  [LoongArch] Lower BlockAddress/JumpTable

This patch uses a unified interface for lower GlobalAddress ConstantPool
BlockAddress and JumpTable.

This patch allows lowering addresses by using PC-relative addressing
for DSO-local symbols, and accessing the address through the global
offset table for DSO-preemptable symbols.

Remove hardcoded `MininumJumpTableEntries` for test lower JumpTable.

Also updated some test cases using ConstantPool, due to the addition of
relocation information.
