Instead of falling back to just the block name (which we won't find),
look for the first element of the block array. We'll deal with the rest
in the backend by arranging for the blocks to be laid out contiguously.
V2: Squashed together patches 3, 5 of V1, plus a naming tweak.

Previously this was a block index with special semantics for -1.
With ARB_gpu_shader5, this need not be a compile-time constant, so
allow any rvalue here and convert the -1 to a NULL pointer.

ir_binop_ubo_load takes unsigned integer operands. However, the array
index used to compute these offsets may be a signed integer. (For
example, see Piglit's spec/glsl-1.40/uniform_buffer/fs-bvec-array).
For some reason, we were missing an ir_binop_i2u cast, and ir_validator
was failing to catch that.
Without this change, ir_builder's type inference code broke for me when
writing a new optimization pass.

In a future patch, this will allow us to enforce invariants when the
interface type is updated.

When reading a column from a row-major matrix, we would slot the single
value read into the vector using an ir_dereference_array of the vector
with a constant index. This will (eventually) get optimized to a
masked-write, so just generate the masked write in the first place.
v2: Remove unused variable 'chan'. Suggested by Ken.

Pretty much all of the compile-time, per-compilation unit block data is
about to get the axe.

The way a variable is tested for this property is about to change, and
this makes the code easier to modify.

v2: Reduce the impenetrable code in emit_ubo_loads() by 23 lines by keeping
the ir_variable as the variable part of the offset from handle_rvalue(),
and track the constant offsets from that with a plain old integer value,
avoiding a bunch of temporary variables in the array and struct handling.
Also, fix file description doxygen.
v3: Fix a row vs col typo, and fix spelling in a comment.
