[LoongArch] Add support for tail call optimization
This patch adds tail call support to the LoongArch backend. When
appropriate, use the `b` or `jr` instruction for tail calls (the
`pcalau12i+jirl` instruction pair when use medium codemodel).
This patch also modifies the inappropriate operand name:
simm26_bl -> simm26_symbol
This has been modeled after RISCV's tail call opt.
