Fix ComputeGenericHash.
ANGLE's internal hash maps would run MurmurHash on c++ structs to
come up with hash values. Since the hash ran on 4 byte words only,
it would have no understanding that sometimes our structs would only
have meaninful data in the first N bytes, and would include the
garbage at the end in the hash calculation. This fixes the problem by
forcing our structs to be aligned at compile-time.
It also adds custom copy operators for a few classes to ensure that
all bits are copied when the struct is initialized, including the
padding.

Implement ANGLE_program_cache_control extensions.
This will give the browsers the ability to control the cache size,
query and populate the contents, and trim cache contents on memory
pressure.

Add platform hook for program cache updates.
This will need to be matched with a corresponding browser-side CL.
It will enable writing out binary shaders to disk.

Use MemoryProgramCache.
Add the member functions for saving and loading from the binary cache,
and hook them into the Program class. Requires that the Renderer
supports the program binary extension.

Use HashingMRUCache in InputLayoutCache.
This simplifies the state management code inside this manager. Also
it should improve the speed of lookups due to using hashing instead
of a tree lookup.

Introduce SizedMRUCache.
This class is an MRU cache for sized objects, like Textures or
Program binaries. It is based on the base::HashingMRUCache type,
and evicts objects automatically.
