and introduce a new Instruction::isIdenticalTo which tests for full
identity, including the SubclassOptionalData flags. Also, fix the
Instruction::clone implementations to preserve the SubclassOptionalData
flags. Finally, teach several optimizations how to handle
SubclassOptionalData correctly, given these changes.

This fixes the counterintuitive behavior of isIdenticalTo not comparing
the full value, and clone not returning an identical clone, as well as
some subtle bugs that could be caused by these.

Thanks to Nick Lewycky for reporting this, and for an initial patch!

of EH stuff going into there, so we can wait to add them all then.

This time there is no additional include of llvm/Config/config.h
at all. Instead I use a hard-coded preprecessor symbol:
LLVM_COMPACTIFY_SENTINELS

(should this work on the self-hosting buildbot, then
 cleanups come next)

should be forced to 32-bits (.long) even on 64-bit architectures. Darwin wants
these bits to be 64-bits (.quad). However, other platforms may disagree.

This is just the info right now and is part of a work-in-progress which needs
this. We'll add the actual *use* of this soon.

 - Dan, please check. If there are parts of the test you think I should strip
   out so it doesn't cause random failures let me know (there are still some PIC
   label numbers in it, for example).

will always return the same value. This isn't currently necessary,
since this code doesn't currently ever get called under circumstances
where it would matter, but it may some day.

to be the entry block of a function, don't sink static allocas
out of it. This fixes PR4775.

rather than separately with new. Move the members above the
TypeMap members to avoid destruction order issues. This fixes
a leak of these objects, and eliminates an extra level of
indirection in Type::getInt32Ty and friends.
