glsl: Rename various ir_* files to lower_* and opt_*.
...
This helps distinguish between lowering passes, optimization passes, and
other compiler code.

glsl2: Don't dead-code eliminate a call where the return value is unused.
...
This showed up since the disabling of inlining at compile time, which
I apparently didn't regenerate piglit summary for.
Fixes:
glsl-deadcode-call.

glsl2: Remove the shader_in/shader_out tracking separate from var->mode.
...
I introduced this for ir_dead_code to distinguish function parameter
outvals from varying outputs. Only, since ast_to_hir's
current_function is unset when setting up function parameters (they're
needed for making the function signature in the first place), all
function parameter outvals were marked as shader outputs anyway. This
meant that an inlined function's cloned outval was marked as a shader
output and couldn't be dead-code eliminated. Instead, since
ir_dead_code doesn't even look at function parameters, just use
var->mode.
The longest Mesa IR coming out of ir_to_mesa for Yo Frankie drops from
725 instructions to 636.

glsl2: Fix the linked version of ir_dead_code.
...
If we don't walk into functions, we won't see any usage of variables
in the functions.

glsl2: Make the dead code handler make its own talloc context.
...
This way, we don't need to pass in a parse state, and the context
doesn't grow with the number of passes through optimization.

glsl2: Use the parser state as the talloc context for dead code elimination.

This cuts runtime by around 20% from talloc_parent() lookups.
