LoongArch: Add new relocs and macro for TLSDESC.
The normal DESC instruction sequence is:
pcalau12i $a0,%desc_pc_hi20(var) #R_LARCH_TLS_DESC_PC_HI20
addi.d $a0,$a0,%desc_pc_lo12(var) #R_LARCH_TLS_DESC_PC_LO12
ld.d $ra,$a0,%desc_ld(var) #R_LARCH_TLS_DESC_LD
jirl $ra,$ra,%desc_call(var) #R_LARCH_TLS_DESC_CALL
add.d $a0,$a0,$tp
