7e2aa91507 glsl2: Add and use new variable mode ir_var_temporary 
This is quite a large patch because breaking it into smaller pieces
would result in the tree being intermitently broken.  The big changes
are:

    * Add the ir_var_temporary variable mode

    * Change the ir_variable constructor to take the mode as a
      parameter and correctly specify the mode for all ir_varables.

    * Change the linker to not cross validate ir_var_temporary
      variables.

    * Change the linker to pull all ir_var_temporary variables from
      global scope into 'main'.

a36334be02 glsl2: Add pass for supporting variable vector indexing in rvalues. 
The Mesa IR needs this to support vector indexing correctly, and
hardware backends such as 915 would want this behavior as well.

Fixes glsl-vs-vec4-indexing-2.
