[Mesa-dev] [PATCH 19/45] i965/fs: Update assertion on copy propagation

[Alejandro Piñeiro]

That assertion was checking that the effective_width * size_element
was a multiple of REG_SIZE. But for HF we are using the full REG_SIZE,
even if the element is smaller.

See "i965: need to allocate as minimum 32-bit register" for more info
