glsl/ir_builder: Add a new swizzle_for_size() function.
This swizzles away unwanted components, while preserving the order of
the ones that remain.

glsl/ir_builder: Add a generic constructor for unary expressions.
I needed to compute logs and square roots in a patch I was working on,
and wanted to use the convenient interface. We already have a similar
constructor for binops; adding one for unops seems reasonable.

glsl: Add a helper for ir_builder to make dereferences for assignments.
v2: Fix writemask setup for non-vec4 assignments.

glsl: Make a little tracking class for emitting IR lists.
This lets us significantly shorten p->instructions->push_tail(ir), and
will be used in a few more places.

glsl: Add common swizzles to ir_builder.
Now we can fold a bunch of our expression setup in ff_fragment_shader
into single-line, parseable commits.
v2: Make it actually work. I wasn't setting num_components in the
mask structure, and not setting up a mask structure is way easier.

glsl: Let ir_builder expressions take un-dereferenced variables.
Having to explicitly dereference is irritating and bloats the code,
when the compiler can detect and do the right thing.
v2: Use a little shim class to produce the automatic dereference
generation at compile time as opposed to runtime, while also
allowing compile-time type checking.

glsl: Create an ir_builder helper for hand-generating IR.
The C++ constructors with placement new, while functional, are
extremely verbose, leading to generation of simple GLSL IR expressions
like (a * b + c * d) expanding to many lines of code and using lots of
temporary variables. By creating a new ir_builder.h that puts simple
generators in our namespace and taking advantage of ralloc_parent(),
we can generate much more compact code, at a minor runtime cost.
v2: Replace ir_instruction usage with just ir_rvalue.
v3: Drop remaining missed as_rvalue() in v2.
