Richard Henderson f55fc1c092 accel/tcg: Add clear_flags argument to page_set_flags 
Expand the interface of page_set_flags to separate the
set of flags to be set and the set of flags to be cleared.

This allows us to replace PAGE_RESET with the PAGE_VALID
bit within clear_flags.

Replace PAGE_TARGET_STICKY with TARGET_PAGE_NOTSTICKY;
aarch64-linux-user is the only user.

Philippe Mathieu-Daudé 82c4d8a3b4 qemu/compiler: Absorb 'clang-tsa.h' 
We already have "qemu/compiler.h" for compiler-specific arrangements,
automatically included by "qemu/osdep.h" for each source file. No
need to explicitly include a header for a Clang particularity.
