LoongArch/GAS: Add support for branch relaxation

For the instructions of R_LARCH_B16/B21, if the immediate overflow,
add a B instruction and R_LARCH_B26 relocation.

For example:

.L1
  ...
  blt $t0, $t1, .L1
    R_LARCH_B16

change to:

.L1
  ...
  bge $t0, $t1, .L2
  b .L1
    R_LARCH_B26
.L2

(cherry picked from commit 1fb3cdd87ec61715a5684925fb6d6a6cf53bb97c)
