glsl: Add a pass to lower bitfield-insert into bfm+bfi.

Browse Source 
i965/Gen7+ and Radeon/Evergreen+ have bfm/bfi instructions to implement
bitfieldInsert() from ARB_gpu_shader5.

v2: Add ir_binop_bfm and ir_triop_bfi to st_glsl_to_tgsi.cpp.
    Remove spurious temporary assignment and dereference.
