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:
-FAST
-SKFOO

Since we no longer have to call out to obtain the buildbot_spec, merge
the two functions in vars API. As a side effect, this applies
default_env to the sync steps as well, which shouldn't have an
appreciable effect on bot behavior.

- builder_name_schema becomes its own recipe module.
- builder_spec, dm, and nanobench flags move into vars module.
- recipe expectation diffs include:
- no more buildbot_spec.py step
- "real" dm and nanobench flags, instead of --dummy-flags
- some inconsequential stuff in visualbench, which is removed anyway.

Break Skia recipe module into:
- skia_vars: defines and stores variables (eg. paths)
- skia_step: utilities for running Skia steps
- skia_flavor: flavor-specific stuff
- skia: top-level setup, checkout, test/perf steps, etc etc
This establishes a saner dependency structure for the recipes; skia_vars
is at the bottom level, skia_step depends on it, skia_flavor depends on
both of them, skia depends on all of the above, and the recipes
themselves may depend on any or all of them.
Next steps:
- Merge buildbot_spec into skia_vars
- Move test_steps and perf_steps from skia recipe_module into
swarm_test and swarm_perf recipes
- Cleaner checkout_steps process
