ir_constant: Don't assert on out-of-bounds array accesses

Several optimization paths, including constant folding, can lead to
accessing an ir_constant array with an out of bounds index.  The GLSL
spec lets us produce "undefined" results, but it does not let us
crash.

Fixes piglit test case glsl-array-bounds-01 and glsl-array-bounds-03.
