99c67603c7 Fix more register allocation sensitive tests.

47bc41b3c3 Remove a test that no longer makes sense. 
It was testing a linear scan feature:

  Test if linearscan is unfavoring registers for allocation to allow
  more reuse of reloads from stack slots.

The greedy register allocator doesn't access any stack slots in this
function, so the linear scan feature was not being tested.

a82f7a687e Let the inline asm 'q' constraint match float, and on 64-bit double too. 
Fixes PR9602!

5fb023bb10 Go ahead and emit the barrier on x86-64 even without sse2. The 
processor supports it just fine.

97b1ec50e3 LICM: Do not loose alignment on promotion 
The promotion code lost any alignment information, when hoisting loads and
stores out of the loop. This lead to incorrect aligned memory accesses. We now
use the largest alignment we can prove to be correct.

f95a1068bd Fix PR10277. 
Remat during spilling triggers dead code elimination. If a phi-def
becomes unused, that may also cause live ranges to split into separate
connected components.

This type of splitting is different from normal live range splitting. In
particular, there may not be a common original interval.

When the split range is its own original, make sure that the new
siblings are also their own originals. The range being split cannot be
used as an original since it doesn't cover the new siblings.

2d266249a6 PR10267: Don't combine an equality compare with an AND into an inequality compare when the AND has more than one use. 
This can pessimize code, inequalities are generally more expensive.

makes one of the tests actually mean something (as the string 'add' will
