memcheck: Remove feature entirely
This patch removes the memcheck feature from the Android emulator
code base. This is for several reasons:
- Supporting the feature impacts many QEMU-specific emulation files
in subtle ways, that make it difficult to refactor this code to
integrate upstream changes.
- The feature only works for ARM (32-bit), has no unit tests, and
generates massive amounts of false positive messages coming
from the platform.
- Barely anyone uses it.
This feature might make a comeback in the future, but this will be
under a different life-form that will have adapted to the new state
of the code.
+ As a bonus, fix the build!

tcg: Upgrade to upstream version.
This switches the full TCG implementation to the upstream version
from the following upstream commit:
1a8e80d7e82aa385ad887dba5d039e399a18264b
Note that this requires completely reqwriting the softmmu_template.h
declarations to adapt to the new world order where all ld/st helpers
now accepts a CPUArchState* value as their first parameter.
+ This also gets rid of the REGPARM macro, which means that on
i386, parameters are now passed on the stack instead of using
registers. As surprising as it is, this doesn't seem to affect
emulation performance in significant ways when starting the
emulator with -force-32bit, compared to the latest SDK emulator
binary. This may be due to the improved binary translator.
Note that this doesn't switch the emulation to use the new
MemoryRegion API, so there are still a few minor differences
with upstream softmmu_*.h headers.
The target-*/ sources have been minimally modified to accomodate
for the changes, and everything seems to work. However, not that
CONFIG_ANDROID_MEMCHECK_MMU hasn't been tested yet.
+ get rid of obsolete softmmu_outside_jit.c
NOTE: There are two important differences with the upstream sources:
- An '#undef small' in tcg.c used to build the Windows binaries
with mingw32 on Linux.
- The declaration of cc_compute_all and cc_compute_c helpers in
target-i386/helper.h use TCG_CALL_NO_SE instead of
TCG_CALL_NO_SE_RWG. Otherwise, it's impossible to boot
an x86 system image properly.

Introduce CPUState.
This patch splits the definitions previously found in CPUArchState,
to place some of them in a common data structure called CPUState,
to mirror upstream.
Note that upstream also makes CPUState a complete QOM object that
derives from DeviceState / DeviceClass, but this patch doesn't do
that. That's why the target-*/cpu-qom.h files, as well as
include/qom/cpu.h are not the real ones from upstream yet.
Future patches will get rid of CPUOldState, which is currently used
as an alias for CPUArchState, but will be replaced entirely by
CPUState, requiring changing the signature of many functions to
match upstream.
QOM-ification will probably happen after that, but may require
a few more patches due to layering / coupling issues.

softmmu: Pass env to load/store routines.
Also define __ldl_mmu et al. in cputlb.c because the TCG-generated
code still calls these directly. Note that these will go once we
actually upgrade TCG to a more recent version.

softmmu_header.h: Pass CPUArchState to helper routines.
This patch modifies the functions defined in softmmu_header.h
to accept a CPUArchState as their first parameter, then it
adjusts every caller appropriately.
This gets up closer to upstream, and remove the obsolete
softmmu_outside_jit.h that was used to do the same thing.

translate-all.c: Multi-level page maps.

The major difference is the implementation of multi-level page
tables (for PageDesc and PhysPageDesc entries). This is a preliminary
requirement to handle 64-bit address spaces properly.

Simple renaming: CPUOldState -> CPUArchState where relevant.
This patch changes a few headers and sources to match upstream when
distinguishing between CPUArchState and CPUOldState (which will become
CPUState soon). For now, both types are identical so this should not
change the generated binaries at all.
