[AArch64] Relax TLS local dynamic traditional into local executable
The linker relaxation logic will be:
Code sequence I (tiny):
0x00 adr x0, :tlsldm:x
0x04 bl __tls_get_addr
|
V
0x00 mrs x0, tpidr_el0
0x04 add x0, x0, TCB_SIZE
Code sequence II (small):
0x00 adrp a0, :tlsldm:x
0x04 add a0, #:tlsldm_lo12:x
0x08 bl __tls_get_addr
|
V
0x00 mrs x0, tpidr_el0
0x04 add x0, x0, TCB_SIZE
0x08 nop
