Subject: i965: Fix assertions about register types for INT DIV in brw_math.
X-Git-Tag: android-x86-4.4-r1~9575

i965: Fix assertions about register types for INT DIV in brw_math.

BRW_MATH_FUNCTION_REMAINDER was missing.  Also, it seems worthwhile to
assert that INT DIV's arguments are signed/unsigned integers.
