For a long time, we've wanted a place to put utility code which isn't
directly tied to Mesa or Gallium internals. This patch creates a new
src/util directory for exactly that purpose, and builds the contents as
libmesautil.la.
ralloc seemed like a good first candidate. These days, it's directly
used by mesa/main, i965, i915, and r300g, so keeping it in src/glsl
didn't make much sense.

Ever since the addition of interface blocks with instance names, we have
had an implicit invariant:
var->type->is_interface() ==
(var->type == var->interface_type)
The odd use of == here is intentional because !var->type->is_interface()
implies var->type != var->interface_type.
Further, if var->type->is_array() is true, we have a related implicit
invariant:
var->type->fields.array->is_interface() ==
(var->type->fields.array == var->interface_type)
However, the ir_variable constructor doesn't maintain either invariant.
That seems kind of silly... and I tripped over it while writing some
other code. This patch makes the constructor do the right thing, and it
introduces some tests to verify that behavior.
v2: Add general-ir-test to .gitignore. Update the description of the
ir_variable invariant for arrays in the commit message. Both suggested
by Paul.
