Original change's description:
> [vm] Remove tcmalloc and malloc profiler.
>
> The standalone VM originally began statically linking tcmalloc to work around bugs in the system malloc for Fiber. Later it used tcmalloc's hooks to implement a profiler, but this is rarely used since it is only available in debug mode, misses early allocations, and often misses late allocations from an exhausted sample buffer. Removing it altogether avoids build complexity around which combinations of compiler/architecture/sysroot support tcmalloc, and reduces binary size.

The sources assignment filter is considered a misfeature of gn
and is planned for removal (see discussion at [1]).
Convert dart BUILD.gn rules to manually filter the files that
are build using explicit `if` expressions. Remove obsolete call
to set_sources_assignment_filter() to filter '*_test.*' files
as no such files are present in the variables used to build the
`sources` value.

This CL switches the ia32 and arm64 builds to use clang by default.
The arm build can't be switched at least until we roll clang to
pick up the fix for https://reviews.llvm.org/D34691.
This CL also changes to use the sysroots from wheezy (and jessie
for arm64) by default so that we can be building/testing locally with
the same setup as we are shipping in the SDK.

This CL begins removing gyp from Dart's tree.
Removing gyp will go in three stages:
1. Remove unused .gyp and .gypi files.
2. Translate *_sources.gypi files to *_sources.gni files
3. Remove //third_party/gyp from DEPS
This CL is stage 1.

This CL also removes some compiler flags that increase space somewhat
that help the profiler find symbols, which isn't included in a PRODUCT
build.

toolchain_prefix was not correctly propagated everywhere it needed to
go. This CL also adds an error to build.py if someone tries to use
--toolchain as it is not supported there.

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.
