According to the documentation in memory.h a ROM memory region will be
backed by RAM for reads, but is supposed to go through a callback for
writes. Currently we were not checking for the existence of the rom_device
flag when determining if we could perform a direct write or not.
To correct that add a check to memory_region_is_direct so that if the
memory region has the rom_device flag set we will return false for all
checks where is_write is set.

As we are only dealing with a blob buffer, use a void pointer
argument. This will let us simplify other APIs.

Only flatview_[read/write]_continue use a byte pointer to increment
an offset. For the users, we are only dealing with a blob buffer.
Use a void pointer argument. This will let us simplify the
address_space API in the next commit.

We currently search both the root and the tcg/ directories for tcg
files:
$ git grep '#include "tcg/' | wc -l
28
$ git grep '#include "tcg[^/]' | wc -l
94
To simplify the preprocessor search path, unify by expliciting the
tcg/ directory.
Patch created mechanically by running:
$ for x in \
tcg.h tcg-mo.h tcg-op.h tcg-opc.h \
tcg-op-gvec.h tcg-gvec-desc.h; do \
sed -i "s,#include \"$x\",#include \"tcg/$x\"," \
$(git grep -l "#include \"$x\""); \
done

Reduce the amount of preprocessor obfuscation by expanding
the text of each of the functions generated. The result is
only slightly smaller than the original.

There are no uses of the *_cmmu names other than the bare wrapping
within the *_code inlines. Therefore rename the functions so we
can drop the inlines.
Use abi_ptr instead of target_ulong in preparation for user-only;
the two types are identical for softmmu.

With the tracing hooks, the inline functions are no longer
so simple. Once out-of-line, the current tlb_entry lookup
is redundant with the one in the main load/store_helper.
This also begins the introduction of a new target facing
interface, with suffix *_mmuidx_ra. This is not yet
official because the interface is not done for user-only.
Use abi_ptr instead of target_ulong in preparation for
user-only; the two types are identical for softmmu.
What remains in cpu_ldst_template.h are the expansions
for _code, _data, and MMU_MODE<N>_SUFFIX.

In the cpu_ldst templates, we already require a MemOp, and it
is cleaner and clearer to pass that instead of 3 separate
arguments describing the memory operation.
