Refactor TLS code and add some tests. The tests and expected results are:
pic | declaration | linkage | visibility |
!pic | declaration | external | default | tls1.ll tls2.ll | local exec
pic | declaration | external | default | tls1-pic.ll tls2-pic.ll | general dynamic
!pic | !declaration | external | default | tls3.ll tls4.ll | initial exec
pic | !declaration | external | default | tls3-pic.ll tls4-pic.ll | general dynamic
!pic | declaration | external | hidden | tls7.ll tls8.ll | local exec
pic | declaration | external | hidden | X | local dynamic
!pic | !declaration | external | hidden | tls9.ll tls10.ll | local exec
pic | !declaration | external | hidden | X | local dynamic
!pic | declaration | internal | default | tls5.ll tls6.ll | local exec
pic | declaration | internal | default | X | local dynamic
The ones marked with an X have not been implemented since local dynamic is not implemented.
