This stops gcc warning about possible uses of an uninitialized
value when compiling with assertions turned off.

Don't spill to the CR save area when using the SVR4 ABI for now.
Don't rely on constants assigned for registers to be in order (they aren't assigned in order).
Make sure CR bits are mapped to the corresponding CR field.

Make CalculateParameterAndLinkageAreaSize() Darwin-specific.
Remove SVR4 specific code from LowerCALL_Darwin() and LowerFORMAL_ARGUMENTS_Darwin().
Rename MachoABI to DarwinABI for consistency.
Rename ELF ABI to SVR4 ABI for consistency.
Factor out common call return lowering between the Darwin and SVR4 ABI.

With the SVR4 ABI on PowerPC, vector arguments for vararg calls are passed differently depending on whether they are a fixed or a variable argument. Variable vector arguments always go into memory, fixed vector arguments are put
into vector registers. If there are no free vector registers available, fixed vector arguments are put on the stack.
The NumFixedArgs attribute allows to decide for an argument in a vararg call whether it belongs to the fixed or variable portion of the parameter list.

it to print them. This gives us column numbers in the diag line. Before:
t.s:4: error: unexpected token in argument list
mov %eax %edx

now:
t.s:4:11: error: unexpected token in argument list
mov %eax %edx

we could do this, doing so requires adjusting the demanded mask and the code isn't
doing that yet. This fixes PR4495

This was considering vector intrinsics to have cost 2, but non-vector
intrinsics to have cost 1, which is backward.
