Attempt to take over all *SAN builds.
MSAN has a lot of coordination required between gn/BUILD.gn and gn_flavor.py.
I'd like to follow up to move more of this into gn/BUILD.gn, to make it easier
to use locally.
The compile steps should be much faster now. We no longer build CMake
and Clang for every run, instead using the clang_linux CIPD package. This
removes the need for all the third_party/externals/llvm/... dependencies.
Similarly, since we're using the clang_linux package, we no longer depend
on Chrome's Clang, and thus no longer need to sync chromium on these bots.
Instead of packaging up MSAN libraries and llvm-symbolizer in the compile
output, I have the test / perf bots also depend on the clang_linux package.
These do not vary from build to build.
No more need for the xsan.blacklist -include hack: Clang, GN, and Ninja
all track changes to xsan.blacklist without our help.
This has the incidental effect of upgrading the compiler used by *SAN
bots from Clang 3.8 to Clang 3.9.

After several different strategies, this one appears to work
well. The basic test:
1) For a variety of drawing techniques, we render fixed size
rectangles. (Solid colors via paint color, bitmap, etc...)
2) For each method in #1, we render to both an sRGB and
WideGamutRGB offscreen surface. (AdobeRGB isn't wide enough
to clearly demonstrate if things are working or not).
3) Use readPixels to fetch the raw (still in wide gamut) pixel
data, then draw that directly to the final canvas.
So, for each pair of squares, they should look clearly
different. Currently, with the GPU backend, only the bicubic
bitmap paths have that behavior. Adding more test cases (and
fixing the ones that are already incorrect) will be the long
tail of gamut transformation.
Current output (with my other patchset, which fixes all
bitmap draws): https://screenshot.googleplex.com/wsL3x7eCtWE.png

I just burned 2 days debugging a confusing interaction between ccache
and the -fsanitize-blacklist argument to Clang. Let's see if we can
live without ccache (swarming affinity + Ninja seems pretty decent).
As a point of reference, the Mac bots have been looking for ccache but
failing to find it. They're proof this will be fine.

I am hoping this makes it easier to get *SAN bots going.
Today we're generating a libcompiler_rt.a that's using a
relocation type that the ld on the bots doesn't know about.
This lld is will know about anything our Clang generates.

The remaining suppression (libwebp) is already covered by the
compile-time blacklist, tools/xsan.blacklist.

This ought to support compiles for now.
Am I picking up my CIPD ndk packages right?
The main thing to note is that I'm passing the target_arch directly through
as target_cpu. This means these bots will have a slightly different naming
convention than we've been using, but it'll agree with what you must type
yourself when using GN to build for Android:
- Arm7 -> arm
- Arm64 -> arm64
- Mips -> mipsel
- Mips64 -> mips64el
- x86 -> x86 (unchanged)
- x86_64 -> x64

This makes it considerably easier to use ccache with the Android NDK.
You can now just set
compiler_prefix = "ccache"
ndk = "/path/to/ndk"
and we'll use the NDK clang, wrapped with ccache.
The name compiler_prefix is stolen from / compatible with Chrome.
If you have ccache, you can just always leave compiler_prefix="ccache" enabled.
This should make it an unusual thing for humans to have to change cc or cxx.

Also:
* Pass through a new property 'patch_storage' to DM/Nanobench/Coverage. This will be used by the different frameworks to figure out if it is Rietveld or Gerrit issue.
* Calculate issue and patchset for Gerrit patches similar to Rietveld.

This shouldn't change any behavior except that the stores to dst
will no longer require 8-byte alignment.
Empirically it seems like we can use 4-byte alignment here,
but u8 (i.e. 1-byte alignment) is always safe.

Adding flags to the end of cc or cxx is pretty useful, but these always end up
on the command line before the GN generated flags, thus setting defaults that
GN will override.
For full flexibility we want to be able to add flags after the flags GN has
added, so that custom flags can override _it_.
I've updated the Fast bots with an example here: if we said cc="clang -O3 ...",
that '-O3' would be overriden later by the default Release-mode '-Os'. By
putting it in extra_cflags, we get the last word: our '-O3' overrides the
default '-Os'.
Another good use case is a hypothetical Actually-Shippable-Release mode. Our
Release mode bundles in tons of debug symbols via '-g'. libskia.a is about 10x
larger than it needs to be when built that way, but it helps us debug the bot
failures immensely. To build a libskia.{a,so} that you'd really ship, you can
now set extra_cflags="-g0" to override '-g'. You could set '-march' flags there
too, '-fomit-frame-pointer', etc.
There are lots of flags that won't matter where they end up in the command line.
To keep everything simple I've put them in extra_cflags with the rest. This means
the only time we change 'cc' or 'cxx' in our recipes is to prefix 'ccache'.

As an experiment, instead of replacing these with -GN twins, take
them over in-place. This should take over:
