[PATCH v5] LoongArch: Add support for TLS descriptors

Add support for TLS descriptors on normal code model and extreme code model. Normal code model instruction sequence: -mno-explicit-relocs: la.tls.desc $r4, s add.d $r12, $r4, $r2 -mexplicit-relocs: pcalau12i $r4,%desc_pc_hi20(s) addi.d $r4,$r4,%desc_pc_lo12(s)
