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.
