The function tm_reclaim_task is only called from the function
__switch_to_tm. This patch merges these two functions to make
it more readable without changing the functionality in any way.

This patch creates a new function called flush_tm_state to flush
the existing transactional memory state from the thread. It also
creates a function called flush_tmregs_to_thread which will then
be used on subsequent patches in this series.
