x32: Add x32 support to -mtls-dialect=gnu2
To add x32 support to -mtls-dialect=gnu2, we need to replace DI with
P in GNU2 TLS patterns. Since DEST set by tls_dynamic_gnu2_64 is in
ptr_mode, PLUS in GNU2 TLS address computation must be done in ptr_mode
to support -maddress-mode=long. Also replace the "{q}" suffix on lea
with "%z0" to support both 32-bit and 64-bit destination register.
Tested on Linux/x86-64.
