"ADDI sp, sp, 24" and "ADDI sp, sp, SZFCSREG" (SZFCSREG = 4) are
misaligning the stack: the ABI mandates a 16-byte alignment. Fix it
by changing the first one to "ADDI sp, sp, 32", and reuse the spare 4th
slot for saving fcsr.

This is mostly based on AArch64 and RISC-V implementation.
Add R_LARCH_TLS_DESC32 and R_LARCH_TLS_DESC64 relocations.
For _dl_tlsdesc_dynamic function slow path, temporarily save and restore
all vector registers.

strlen-lasx is implemeted by LASX simd instructions(256bit)
strlen-lsx is implemeted by LSX simd instructions(128bit)
strlen-align is implemented by LA basic instructions and never use unaligned memory acess

The following usage of macro LEAF/ENTRY are all feasible:
1. LEAF(fcn) -- the align value of fcn is .align 3(default value)
2. LEAF(fcn, 6) -- the align value of fcn is .align 6
