5f72fa5701 R600: Remove alu-split.ll test
The purpose of this test was to check boundary conditions for the size
of an ALU clause.  This test is very sensitive to changes to the
optimizer or scheduler, because it requires an exact number of ALU
instructions in order to remain valid.  It's not good to have a test
this sensitive, because it is confusing to developers who implement
optimizations and then 'break' the test.

I'm not sure if there is a good way to test these limits using lit, but
if I can come up with replacement test that isn't as sensitive I'll add
it back to the tree.

73e44d8ae4 R600/SI: Report unaligned memory accesses as legal for > 32-bit types
In reality, some unaligned memory accesses are legal for 32-bit types and
smaller too, but it all depends on the address space.  Allowing
unaligned loads/stores for > 32-bit types is mainly to prevent the
legalizer from splitting one load into multiple loads of smaller types.
