This new option is the default, but it is useful to have a flag to override
-mno-implicit-float by putting -mimplicit-float later on the command line.

This required some tedious reordering to match clang's order.
Presumably these ObjC tests were generated based on llvm-gcc's output
ordering.

Apple's kernel engineers have been expecting this behavior even though
we've never implemented it before, as far as I can tell. In recent months,
clang has gotten better at using vector instructions to optimize memcpy-like
operations, and that has exposed problems when vector/floating-point
instructions are used in kexts that don't support that. This behavior also
matches what Apple's GCC did for PowerPC targets.

For x86 targets, we've been using the -msoft-float option to control passing
the no-implicit-float option to cc1. Since the -mno-implicit-float option is
now accepted by the driver, this just makes it work for x86 the same as it
does for ARM targets.
