Zachary Anderson 44a04f18f9 Use tcmalloc on Linux 
Statically linking in the tcmalloc code is enough
to override the built-in malloc. I have this set up to
exclude the code for collecting heap profiles in a
Product build. There's still about a 230KB increase in
binary size, though. I think this isn't a big problem
since right now this is enabled only for server Linux.

product binary size:
before x64: 9569600
after  x64: 9807840
increase: 238240 (2.5%)

Zachary Anderson 3d7202bad3 DBC: Adds simdbc64 target, adds arm64 arithmetic overflow logic 
There were differences between linux gcc, android gcc,
MacOS clang, and 32 vs. 64-bit w.r.t the __builtin
functions for detecting arithmetic overflow. I couldn't get
them all working at the same time. Instead, I removed them,
and changed to always use the inline assembly. This works
in all the configurations above.

This change also adds a simdbc64 target for building simdbc
for 64-bit, and sets up the android targets. simdbc targets
arm, and simdbc64 targets arm64. You can build them with:

$ ./tools/build.py -m release -a simdbc{64} --os=android runtime

Florian Schneider 64e71a0b2e VM: Make more globals constant where easily possible. 
Remove -fdata-section again from the Linux build configuration: It prevented
some optimizations in gcc and clang - fewer things were recognized as constants.

Add const to pointers/arrays in some places to help compilers with determining
what is a constant.  A common pattern is strlen of a string literal const char*,
or an array of function pointers.

Tested with gcc 4.8.4 / clang 3.4 and improves code qualtiy + reduces binary size.

Florian Schneider f0a35b3260 VM: Add dart_precompiled build target, a standalone VM without the JIT compiler. 
This removes most of the compiler-related code from dart_precompiled:
x64 stripped binary size 13M -> 9.1M
ARM stripped binary size 12M -> 8.3M

The precompiled build defines the DART_PRECOMPILED macro. This
stubs out the public interface to the compiler/parser with empty
function bodies.

Use gcc options -ffunction-sections and --gc-sections to make the linker remove
unused functions/symbols.

zra@google.com 3508d336dd Simplifies standalone VM Android build. 
This change also avoids the need to
do another 'gclient runhooks' when switching
between Android and Linux builds, and between
IA32 and ARM Android builds.

gyp does not allow 'libraries' sections inside of
configurations. Therefore, since some architecture
specific paths, libraries, etc. must be specified
on the Android NDK's linker command line, to avoid
re-gyping when switching between Android IA32 and ARM,
this change moves the architecture specific linker
flags to a script, android_link.py.

To avoid re-gyping when swtiching between Linux and
Android, this change creates new configurations
that specify the target OS as well as the the target
architecture, e.g. ReleaseLinuxARM or ReleaseAndroidARM
instead of ReleaseARM.

This change also adds a --toolchain flag to build.py,
and removes obsoleted logic for setting up the Android
build.

zra@google.com dae5068650 Enables cross-compilation of the VM for ARM. 
Uses the "toolset" feature of gyp to build the dart VM
for ARM, but restricts building of snapshot generation
to the host machine.

For generated source files, it also changes to using
LIB_DIR instead of SHARED_INTERMEDIATE_DIR to avoid
generation of duplicate Makefile rules (gyp doesn't
know that generated source files from toolchains it
thinks are different will be the same.)

loaded libraries to lookup the API symbols in the binary. We
use that for native extensions.
