[Mesa-dev] [PATCH 10/22] i965/meta: Unscalarize some calculations

[Ian Romanick]

From: Ian Romanick <ian.d.romanick at intel.com>

After the previous changes, it just looked weird.  Everyone that saw it
would wonder whether there was some magic reason it had to be that way.
At the end of the day, it should produce identical code.

   text	   data	    bss	    dec	    hex	filename
5126424	 209888	  28120	5364432	 51dad0	before-64/lib64/i965_dri.so
5126296	 209888	  28120	5364304	 51da50	after-64/lib64/i965_dri.so
