Turns out that doing this by hand is easier than using autoreconf:-).

type as the vector element type: allow them to be of
a wider integer type than the element type all the way
through the system, and not just as far as LegalizeDAG.
This should be safe because it used to be this way
(the old type legalizer would produce such nodes), so
backends should be able to handle it.  In fact only
targets which have legal vector types with an illegal
promoted element type will ever see this (eg: <4 x i16>
on ppc).  This fixes a regression with the new type
legalizer (vec_splat.ll).  Also, treat SCALAR_TO_VECTOR
the same as BUILD_VECTOR.  After all, it is just a
special case of BUILD_VECTOR.

Configure was not actually regenerated, but the change last time only touched
this one line, so I'm being lazy and cheating by fixing it manually.

it improves the code, getting rid of all spills).
I don't understand the optimization well enough to
rescue the test, so XFAILing.

my earlier patch to this code only fixed half of it.

Use a safer iterator interface and get rid of std C++ library misuse.
This fixes a --enable-expensive-checks problem.

Regenerate configure.

Add a --enable-profiling option to configure to build Debug+Profile and
Opt+Profile tools.  Now we can profile any kind of flavor we build.

Two more instructions, but fewer memory accesses. It can also open up
opportunities for more optimizations.
