function prototype into a call to a varargs prototype. We do
allow the xform if we have a definition, but otherwise we don't
want to risk that we're changing the abi in a subtle way. On
X86-64, for example, varargs require passing stuff in %al.

More fcopysign correctness and performance fix.
...
The previous codegen for the slow path (when values are in VFP / NEON
registers) was incorrect if the source is NaN.
The new codegen uses NEON vbsl instruction to copy the sign bit. e.g.
vmov.i32 d1, #0x80000000
vbsl d1, d2, d0
If NEON is not available, it uses integer instructions to copy the sign bit.

Keep track of how many times a live range has been dequeued, and prioritize new ranges.
...
When a large live range is evicted, it will usually be split when it comes
around again. By deferring evicted live ranges, the splitting happens at a time
when the interference pattern is more realistic. This prevents repeated
splitting and evictions.

Be more aggressive about evicting interference.

Use interval sizes instead of spill weights to determine if it is legal to evict
interference. A smaller interval can evict interference if all interfering live
ranges are larger.
Allow multiple interferences to be evicted as along as they are all larger than
the live range being allocated.
Spill weights are still used to select the preferred eviction candidate.

Change the RAGreedy register assignment order so large live ranges are allocated first.

This is based on the observation that long live ranges are more difficult to
allocate, so there is a better chance of solving the puzzle by handling the big
pieces first. The allocator will evict and split long alive ranges when they get
in the way.
RABasic is still using spill weights for its priority queue, so the interface to
the queue has been virtualized.

In other words, do not keep track of argument's location. The debugger (gdb) is not prepared to see line table entries for arguments. For the debugger, "second" line table entry marks beginning of function body.
This requires some coordination with debugger to get this working.

- The compiler needs to accurately mark prolog_end in line table entries (at -O0 and at -O1+)

itself without going via a phi node then we could return false here in

the invoke, then phi2 would be deleted but not the invoke instruction and
