glsl: Fix broadcast_index of lower_variable_index_to_cond_assign.
It's trying to get an int smeared across all channels, not trying to
get a 1:1 mapping of a subset of a vector's channels. This usually
ended up not mattering with ir_to_mesa, since it just smears floats
into every chan of a vec4.
Fixes:
glsl1-temp array with swizzled variable indexing
(cherry picked from commit 668cdbe12958247f4a563c362dbf3247de7ccc3f)
