D3D11: Fix varying packing with structs.
Previously we would try to pass an entire struct through HLSL's
shader interface. Instead, split this off as if each field was
its own variable, which seems to be spec compliant (see ESSL 3.10).
In the future we may want to fix register packing to use specific
components of float4/int4/uint4 HLSL registers. This could also fix
the remaining bugs in the SM3 packing.

D3D: Rework varying packing code.
In D3D we pack varyings by making a register map, and using the
recommended GLSL ES algorithm to reserve register space. We use
this map to assign row and column slots to each varying and then
produce a semantic index value.
The existing scheme had a number of bugs, and was failing several
angle_end2end_tests. The new design cleans up the code somewhat
and uses a different counting scheme for the semantic indexes:
just sort the varyings in packing order and use a simple
incrementing semantic index per varying. In SM4+, the HLSL compiler
sorts and packs the varyings correctly itself, and in SM3, handle
the cases we don't support by returning an error instead of a D3D
compiler link error.
Also refactor how we store varying information for TF Feedback/
StreamOut. Only store the necessary D3D information, instead of
extra information like the name and type.
This fixes several tests in GLSLTest/*. This also will allow us to
fix interpolation qualifier packing and the structure packing in
HLSL, which seems to work differently than the rest of the varying
types.

ProgramD3D: Move some common code into a Metadata class.
This metadata class captures some of our commonly referenced but also
complex flats into a shared place. We can then re-use them in the
semantic code, the DynamicHLSL linking code, and the program code.
Refactoring patch only.
