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.

     addq  %rax, %r12
     addq  %r13, %r12

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

and argument positions but only to the overloaded intrinsic parameters.
Keep a separate list of these overloaded parameters in CodeGenTarget.cpp
so they can be resolved easily.  Remove assertions from IntrinsicEmitter.cpp:
they were harmless but confusing, and the assertions elsewhere in TableGen
will catch any incorrect values.

locks must be matched with unlocks.  Also, use calloc to allocate the
block so that it is properly zero'd.  Thanks to Nick Kledzik for

COPY_TO_REGCLASS node. In the case that the copy is coalesced
away, the dependence should be on the user of the copy, rather
than the copy itself.

Do not treat beginning of inlined scope as beginning of normal function scope if the location info is missing.

have pointer types, though in contrast to C pointer types, SCEV
addition is never implicitly scaled. This not only eliminates the
need for special code like IndVars' EliminatePointerRecurrence
and LSR's own GEP expansion code, it also does a better job because
it lets the normal optimizations handle pointer expressions just
like integer expressions.

Also, since LLVM IR GEPs can't directly index into multi-dimensional
VLAs, moving the GEP analysis out of client code and into the SCEV
framework makes it easier for clients to handle multi-dimensional
VLAs the same way as other arrays.

Some existing regression tests show improved optimization.
test/CodeGen/ARM/2007-03-13-InstrSched.ll in particular improved to
the point where if-conversion started kicking in; I turned it off
for this test to preserve the intent of the test.
