Trim pre-Zygote fork, fix under-estimate of heap limit.
Card scanning uses dvmHeapSourceGetValue to scan from the heap base to
the total foot print of the heap. Trimming the Zygote may lower the
footprint of the heap by creating a hole in the middle. This hole is
unaccounted for in the card scanning leading to missed dirty cards.
This was a regression introduced by:
https://android-review.googlesource.com/#/c/41728/
as it didn't #define MORECORE_CANNOT_TRIM 1 that was previously defined
here:
https://android-review.googlesource.com/#/c/41731/4/libcutils/mspace.c
Introduce a notion of dvmHeapSourceGetLimit so that card scanning
doesn't rely on footprint. Trim the heap before forking the Zygote. This
change continues to enable morecore trimming of mspaces.

Zygote now mounts a tmpfs over any existing /storage contents, giving
it a clean slate for its bind mounts. This supports a symlink that
enables legacy /sdcard paths for shell users. Move to using paths
defined from environment variables, instead of header files.

We hold the heap lock during the calloc of an object in the GCed heap.
We do a non-volatile store following this for the clazz, this may lead to a
race where an object is allocated but appears to have no clazz.

- changes to compiler/template/ that result in the
compiler templates to live in the non-executable
.data.rel.ro section (this code is never executed

Without the fix the compiler is still safe since the offending memory access

Fix Method.getParameterAnnotations.
The dex format represents parameter annotations using an
annotation_set_ref_item for each parameter. According to the spec,
the item's annotation_offset can be "0 if there are no annotations for this
element". The Dalvik VM accepts 0 values in the verification step,
but Method#getParameterAnnotations then crashes with a segmentation fault.

[X86] X86 trace JIT compiler support
This patch provides a fully functional x86 trace JIT compiler for Dalvik
VM. It is built on top of the existing x86 fast interpreter
with bug fixes and needed extension to support trace JIT interface. The
x86 trace JIT code generator was developed independent of the existing
template-based code generator and thus does not share exactly the same
infrastructure. Included in this patch are:
* Deprecated and removed the x86-atom fast interpreter that is no
longer functional since ICS.
* Augmented x86 fast interpreter to provide interfaces for x86 trace JIT
compiler.
* Added x86 trace JIT code generator with full JDWP debugging support.
* Method JIT and self-verification mode are not supported.
The x86 code generator uses the x86 instruction encoder/decoder library
from the Apache Harmony project. Additional wrapper extension and bug
fixes were added to support the x86 trace JIT code generator. The x86
instruction encoder/decoder is embedded inside the x86 code generator
under the libenc subdirectory.

Avoid sign extension in packed-switch.
This code (at least in the ARM version) is trying to assign to r0 and r1
from C by returning a 64-bit result. The mistaken use of signed integers
for pointers can lead to sign extension if the JIT code cache is at a
sufficiently high address.
