This patch reshuffles the colors used for the various tick categories in
the visualization. Category rows are now light gray. The new colors are
taken from the Material palette. See screenshots on the associated bug.

This patch also labels the GC bucket as such, instead of having the same
label as uncategorized C++.

With the origin trial for WebAssembly threads, threads can be turned on
and off by the embedder depending on the context we are currently in.
With this CL we call the embedder callback stored on the isolate to
determine whether threads are enabled in the current context or not.

Design decision:
I decided to extend the {WasmFeaturesFromIsolate} function to ask the
embedder if WebAssembly threads are enabled. This is the function which
defines dynamically which features are turned on. It would be awkward
to have two such functions, one which calls the embedder and one which
does not.
A downside is that in WasmJs::Install the embedder does not seem to be
ready to be called. That's why I changed the code there to call
{WasmFeaturesFromFlags} instead.

This CL implements several things needed for full SIMD BE support in WASM:
* Global variables are now kept in little-endian order as per specification
* Added support for SIMD on BE in wasm interpreter
* Fixed several tests that didn't work on BE because input or output
  data were not using LE in-memory layout

This reverts commit 5b434929.

Changes after the original CL:
- Right-trimming registers the array as an object with invalidated
  slots.
- Left-trimming moves the array start in the invalidated slots map.

Original change's description:
> Fix invalidation of old-to-old slots after object trimming.
>
> A recorded old-to-old slot may be overwritten with a pointer to a new
> space object. If the object containing the slot is trimmed later on,
> then the mark-compactor may crash on a stale pointer to new space.
>
> This patch ensures that:
> 1) On trimming of an object we add it to the invalidated_slots sets.
> 2) The InvalidatedSlotsFilter::IsValid returns false for slots outside
>    the invalidated object unless the page was already swept.
>
> Array left-trimming is handled as a special case because object start
> moves and cannot be added to the invalidated set. Instead, we clear
> the freed memory so that the recorded slots contain Smi values.

In Trunc_ul_d and Trunc_ul_s, register result is optional and
this is signaled by setting its value to invalid.
AreAliased expects that all registers are valid. For this reason
the compilation fails in snapshot generation mode.

This CL fixes the issue by calling AreAliased macro only
with valid registers.

Reason for revert:  This is not sound as long as cast<FixedDoubleArray>() doesn't do the same.

This adds a new command abstraction for running commands on Android
using dockered devices on swarming.

The new abstraction handles pushing all required files to the device.
The logic used for pushing and running is reused from the perf runner.

This adds only the mjsunit test suite. Others will be handled in
follow up CLs. The suite logic is enhanced with auto-detection of files
to be pushed to devices, for e.g. load or import statements.

Some test cases need an extra resource section for specifying required
files.

Remaining failing tests are marked in the status files for later
triage.
