Fix a bug in spill weight computation. If the alias is a super-register, and the super-register is in the register class we are trying to allocate. Then add the weight to all sub-registers of the super-register even if they are not aliases.
e.g. allocating for GR32, bh is not used, updating bl spill weight.
     bl should get the same spill weight otherwise it will be choosen
     as a spill candidate since spilling bh doesn't make ebx available.
This fix PR2866.

Fix codegen to compute the size of an allocation by multiplying the
size by the array amount as an i32 value instead of promoting from
i32 to i64 then doing the multiply.  Not doing this broke wrap-around
assumptions that the optimizers (validly) made.  The ultimate real
fix for this is to introduce i64 version of alloca and remove mallocinst.

This fixes PR3829
