glsl: Use the ir_intrinsic_* enums instead of the __intrinsic_* name strings

   text	   data	    bss	    dec	    hex	filename
6038043	 283160	  28608	6349811	 60e3f3	lib64/i965_dri.so before
6036507	 283160	  28608	6348275	 60ddf3	lib64/i965_dri.so after

v2: s/ir_intrinsic_atomic_sub/ir_intrinsic_atomic_counter_sub/.  Noticed
by Ilia.

v3: Silence unhandled enum in switch warnings in st_glsl_to_tgsi.
