[Mesa-dev] [PATCH 18/23] i965/fs: Remove fs_reg::retype.

[Francisco Jerez]

There doesn't seem to be any reason for it to be a method, and it's
surprising that the expression 'reg.retype(t)' doesn't retype its
object but rather it creates a temporary with the new type.  Use
'retype(reg, t)' instead.
