The live range of a register defined by an early clobber starts at the use slot,
not the def slot.

Except when it is an early clobber tied to a use operand. Then it starts at the
def slot like a standard def.

to create the special Neon vector types.  These are intended to be used in
Clang's version of <arm_neon.h> to define special Neon vector types that will
be mangled according to ARM's ABI.

This is needed for Neon types when it is most natural to define them in terms
of a typedef.  For example, Neon poly8_t is a typedef for "signed char", and
we want to define polynomial vectors as vectors of that typedef.  Without this
change, the result will be a generic GCC-style vector.  I think this is safe
for other vector types as well, but I would appreciate a review of this.

one of the special Neon types.  We'll check for invalid Neon vectors when
they are created, so there's no point in handling them when mangling.

Remove invalid assertion from CFG builder.  When building the CFG pieces for a ternary '?' expression,
it is possible for the confluence block to only have a single predecessor due to calls to 'noreturn'
functions.  Fixes assertion failure reported in PR 8619.

live ranges for the spill register are also defined at the use slot instead of
the normal def slot.

This fixes PR8612 for the inline spiller. A use was being allocated to the same
register as a spilled early clobber def.

This problem exists in all the spillers. A fix for the standard spiller is
forthcoming.
