Inline soinfo::get_tls

The run-time of dl_iterate_phdr can be noticeable for exception-handling.

e.g. I tested extest on the GitHub issue by:
 - disabling the dlpi_subs/dlpi_adds-based caching in libgcc
 - adding a weaker "load base hint" caching in libgcc that doesn't need
   the dlpi_subs/dlpi_adds fields, but still has to iterate over every
   module to validate a cache hit

extest throws 10000 exceptions, and I saw a regression from ~1550ms
runtime on Q to about ~1950ms on master. This CL reduces the regression to
about ~1700ms.
