Fix markdown in the description...


In general dynamic/local dynamic TLS models, with -fno-plt,

- x86: emit `calll *___tls_get_addr at GOT(%ebx)` instead of `calll ___tls_get_addr at PLT`
- x86_64: emit `callq *__tls_get_addr at GOTPCREL(%rip)` instead of `callq __tls_get_addr at PLT`

Reorganize the code by separating 32-bit and 64-bit.
