This patch adds support for TLSGD relocations to XCOFF objects:

- Add branch abloste reloction R_RBA, R_TLS relocation for the variable offset for the tlsgd model and R_TLSM for the region handle for the tlsgd model
- Put .__tls_get_addr symbol in the ProgramCodeSects with XTY_ER property
- Fix the switch section failure between the TC Entry of variable offset and region handle
- Add new variantKinds for the symbol's variable offset and region handle
- Print the proper relocation specifier @gd in the asm streamer when emitting the TC Entry for the variable offset for the symbol
