d6d1fd2973 accel/tcg: Rename tb_invalidate_phys_page_range and drop end parameter
This function is is never called with a real range,
only for a single page.  Drop the second parameter
and rename to tb_invalidate_phys_page.

67aabbb312 accel/tcg: Rename tb_invalidate_phys_page
Rename to tb_invalidate_phys_page_unwind to emphasize that
we also detect invalidating the current TB, and also to free
up that name for other usage.

4c88475c9f accel/tcg: Remove duplicate store to tb->page_addr[]
When we added the fast path, we initialized page_addr[] early.
These stores in and around tb_page_add() are redundant; remove them.

8516e2a92c accel/tcg: Drop cpu_get_tb_cpu_state from TARGET_HAS_PRECISE_SMC
The results of the calls to cpu_get_tb_cpu_state,
current_{pc,cs_base,flags}, are not used.
In tb_invalidate_phys_page, use bool for current_tb_modified.
