aarch64: optimize _dl_tlsdesc_dynamic fast path
Remove some load/store instructions from the dynamic tlsdesc resolver fast path. This gives around 20% faster tls access in dlopened shared libraries (assuming glibc ran out of static tls space). * sysdeps/aarch64/dl-tlsdesc.S (_dl_tlsdesc_dynamic): Optimize.
