Improve TARGET_IRA_CHANGE_PSEUDO_ALLOCNO_CLASS target hook.
Improve TARGET_IRA_CHANGE_PSEUDO_ALLOCNO_CLASS target hook. It turns out there
is another case where the register allocator uses the union of register classes
without checking that the cost of the resulting register class is lower than
both (see https://gcc.gnu.org/ml/gcc-patches/2015-12/msg01765.html ). This
happens when the cost of the best and alternative class are both lower than the
memory cost. In this case we typically end up with ALL_REGS as the allocno
class, which almost invariably results in bad allocations with many redundant
int<->FP moves (which are expensive on various cores). AArch64 is affected by
this significantly due to supporting many scalar integer operations in SIMD.
Currently the TARGET_IRA_CHANGE_PSEUDO_ALLOCNO_CLASS hook forces the class to
GENERAL_REGS if the allocno class is ALL_REGS and the register has an integer
mode. This is bad if the best class happens to be FP_REGS. To handle this
case as well, an extra argument is needed in the hook to pass the best class.
If the allocno class is ALL_REGS, but the best class isn't, we use the best
class instead (rather than using the mode to force to GENERAL_REGS or FP_REGS).
Previously this might happen:
r79: preferred FP_REGS, alternative GENERAL_REGS, allocno GENERAL_REGS
a1 (r79,l0) best GENERAL_REGS, allocno GENERAL_REGS
a1(r79,l0) costs: CALLER_SAVE_REGS:5000,5000 GENERAL_REGS:5000,5000
FP_LO_REGS:0,0 FP_REGS:0,0 ALL_REGS:10000,10000 MEM:9000,9000
The proposed allocno is ALL_REGS (despite having the highest cost!) and is then
forced by the hook to GENERAL_REGS because r79 has integer mode. However
FP_REGS has the lowest cost. After this patch the choice is as follows:
r79: preferred FP_REGS, alternative GENERAL_REGS, allocno FP_REGS
a1 (r79,l0) best FP_REGS, allocno FP_REGS
As a result it is now no longer a requirement to use register move costs that
are larger than the memory move cost. So it will be feasible to use realistic
costs for both without a huge penalty.

This patch adds support for the TARGET_IRA_CHANGE_PSEUDO_ALLOCNO_CLASS hook.
When the cost of GENERAL_REGS and FP_REGS is identical, the register allocator
always uses ALL_REGS even when it has a much higher cost. The hook changes the
class to either FP_REGS or GENERAL_REGS depending on the mode of the register.
This results in better register allocation overall, fewer spills and reduced
codesize - particularly in SPEC2006 gamess.
