[Piglit] [PATCH] Add a test for FDO bug #99154

[Niels Ole Salscheider]

builtin_builder::binop creates variables named x and y. Because of
a bug these variables had mode ir_var_auto instead of
ir_var_temporary. In this case, the variable names can collide when
the function is inlined later on.
Linking will fail in this test if this is the case.
