Since 2ac01d6daf, this function does only two things: assert a
lock is held, and call tcg_tb_alloc. It is used exactly once,
and its user has already done the assert.

This fixes a segmentation fault in icount mode when executing
from an IO region.
TB is marked as CF_NOCACHE but tb->orig_tb is not initialized
(equals previous value in code_gen_buffer).
The issue happens in cpu_io_recompile() when it tries to invalidate orig_tb.

Using uintptr_t instead of target_ulong meant that, for 64-bit guest
and 32-bit host, we truncated the guest address comparator and so may
not hit the tlb when we should.

This eliminates a set of runtime shifts. It turns out that we
require TARGET_PAGE_MASK more often than TARGET_PAGE_SIZE, so
redefine TARGET_PAGE_SIZE based on TARGET_PAGE_MASK instead of
the other way around.

There are some uint64_t uses that expect TARGET_PAGE_MASK to
extend for a 32-bit, so this must continue to be a signed type.
Define based on TARGET_PAGE_BITS not TARGET_PAGE_SIZE; this
will make a following patch more clear.
This should not have a functional effect so far.

Using a variable that is declared "const" for this tells the
compiler that it may read the value once and assume that it
does not change across function calls.
For target_page_size, this means we have only one assert per
function, and one read of the variable.
This reduces the size of qemu-system-aarch64 by 8k.
