Don't constant propagate byval pointers, since they are not really pointers, but
rather structs passed by value.
This fixes PR5038.

Merge from mainline.2009-08-31T06:32:45ZTanya Lattnertonic@nondot.org2009-08-31T06:32:45Zurn:sha1:afeffeb1d700b94221435f716becfb968a624514
Rename Instruction::isIdenticalTo to Instruction::isIdenticalToWhenDefined,
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!

by hand, and fix a few places that were using hasInitializer() that
appear to depend on the initializer value.

Don't access the first element of a potentially empty2009-08-17T14:33:27ZDuncan Sandsbaldrick@free.fr2009-08-17T14:33:27Zurn:sha1:fa6a1cf1ed4282145269b12578f687b3869d6476
vector (&Formals[0]). With this change llvm-gcc builds
with expensive checking enabled for C, C++ and Fortran.
While there, change a std::vector into a SmallVector.
This is partly gratuitous, but mostly because not all
STL vector implementations define the data method (and
it should be faster).
