Limit the search space in RAGreedy::tryEvict().
When tryEvict() is looking for a cheaper register in the allocation
order, skip the tail of too expensive registers when possible.

Speed up the AllocationOrder class a bit.
Allow the central functions to be inlined, and use the argumentless
isHint() function when possible.

Sort includes for all of the .h files under the 'lib' tree. These were
missed in the first pass because the script didn't yet handle include
guards.
Note that the script is now able to handle all of these headers without
manual edits. =]

Use the new getRegAllocationHints() hook from AllocationOrder.
This simplifies the hinting code quite a bit while making the targets
easier to write at the same time.

Use MCPhysReg for RegisterClassInfo allocation orders.
This saves a bit of memory.

Get allocation orders from RegisterClassInfo when possible.
Only target-dependent hints require callbacks. The RCI allocation order
has CSR aliases last according to their order of appearance in the
getCalleeSavedRegs list. This can depend on the calling convention.
This way, AllocationOrder::next doesn't have to check for reserved
registers, and CSRs are always allocated last, even with weird calling
conventions.

Switch AllocationOrder to using RegisterClassInfo instead of a BitVector
of reserved registers.
Use RegisterClassInfo in RABasic as well. This slightly changes som
allocation orders because RegisterClassInfo puts CSR aliases last.

Try harder to get the hint by preferring to evict hint interference.

Add an AllocationOrder class that can iterate over the allocatable physical
registers for a given virtual register.
Reserved registers are filtered from the allocation order, and any valid hint is
returned as the first suggestion.
For target dependent hints, a number of arcane target hooks are invoked.
