[X86] Support -fno-plt __tls_get_addr calls
In general dynamic/local dynamic TLS models, with -fno-plt,
* x86: emit `calll *___tls_get_addr@GOT(%ebx)` instead of `calll ___tls_get_addr@PLT`
Note, on x86, if we can get rid of %ebx as the PIC register,
it may be better to use a register not preserved across function calls.
* x86_64: emit `callq *__tls_get_addr@GOTPCREL(%rip)` instead of `callq __tls_get_addr@PLT`
Reorganize the code by separating 32-bit and 64-bit.
