- In the case when the quotient and remainder of a divide are used a DIV

they are both lowered to IDIVs and CSE removes the redundant IDIV instruction,
using the quotient and remainder from the first IDIV. However,
due to this optimization CSE is not able to eliminate redundant
IDIV instructions because they are located in different basic blocks.
This is overcome by calculating both the quotient (DIV) and remainder (REM)
in each basic block that is inserted by the optimization and reusing the result
values when a subsequent DIV or REM instruction uses the same operands.

Only legalise a VSELECT in to bitwise operations if the vector mask bool is zeros or all ones.  A vector bool with just ones isn't suitable for masking with.

No test case unfortunately as i couldn't find a target which fit all
the conditions needed to hit this code.
