[PATCH v2 0/1] LoongArch: Add support for the third expression of .align for R_LARCH_ALIGN

[mengqinggang]

If the symbol index is not zero, the addend is used to represent
the first and the third expressions of the .align.

The lowest 8 bits are used to represent the first expression.
Other bits are used to represent the third expression.

The addend of R_LARCH_ALIGN for ".align 5, ,4" is 0x405.
The addend of R_LARCH_ALIGN for ".balign 32, ,4" is 0x405.

Changes from v1:
  Set the address of symbol in R_LARCH_ALIGN to zero.
