When mixing SSE and x87 codegen, it's possible to
have situations where an SSE instruction turns into
multiple blocks, with the live range of an x87
register crossing them.  To do this correctly make
sure we examine all blocks when inserting
FP_REG_KILL.  PR 1697.  (This was exposed by my
fix for PR 1681, but the same thing could happen
mixing x87 long double with SSE.)

use typenames equivalent to
(u)intval, because latter are not
present in older caml/mlvalues.h
(e.g. 2004/07/07, 1.48.6.1)

Using this as a workaround for now,
until --without-ocaml works
or we settle on a better solution

Excuse me.

Fix optimization. %x = sub %x, %y does not imply that %y is zero.

More long double fixes.  x86_64 should build now.

Avoid referencing deleted instruction.

Previously GraphWriter assumed operator*() for node_iterator always
returned a reference type.  This patch allows operator*() to return a
non-reference type while still maintaining the old behavior when it
does return a reference type.

This patch was motivated when I tried to use "df_iterator" (see
llvm/ADT/DepthFirstIterator.h) as a "node_iterator", as df_iterator
does not return a reference type and thus we would get a compilation
error when trying to take the address of a temporary.

PSHUFDmi, etc. are actually folding a load, not a store.

Add a flag to mark a dirty cache entry.  This is not yet used, but will eventually
help non-local memdep caching.
