the section or the visibility from one global
value to another: copyAttributesFrom. This is
particularly useful for duplicating functions:
previously this was done by explicitly copying
each attribute in turn at each place where a
new function was created out of an old one, with
the result that obscure attributes were regularly
forgotten (like the collector or the section).
Hopefully now everything is uniform and nothing
is forgotten.

Analysis/ConstantFolding to fold ConstantExpr's, then make instcombine use it
to try to use targetdata to fold constant expressions on void instructions.
Also extend the icmp(inttoptr, inttoptr) folding to handle the case where
int size != ptr size.

returning false for struct or array types.
This commit doesn't change the behavior of Type::isFirstClassType.

1. The "JITState" object creates a PassManager with the ModuleProvider that the
jit is created with. If the ModuleProvider is removed and deleted, the
PassManager is invalid.
2. The Global maps in the JIT were not invalidated with a ModuleProvider was
removed. This could lead to a case where the Module would be freed, and a
new Module with Globals at the same addresses could return invalid results.

"-Wshorten-64-to-32 -Werror" will cause a failure when compiling this complex
program:
#include <string>
class Path {
mutable std::string path;
public:
bool operator == (const Path &that) {
return path == that.path;
}
};
Using strcmp gets us past this annoying error.

in some cases on Darwin, so we need both. The intent
is that "common" will behave identically to "weak" unless
somebody changes their target to do something else.

DAG instruction selectors. Introudce a dedicated header file for this part:
include/llvm/CodeGen/DAGISelHeader.h
TableGen now only generates the include preprocessor directive to include this
new header.
This is a preparation for supporting multiple implementations of instruction
selectors in the future.

Do not rely on std::swap<Use>, provide a (faster) member function instead.
This change is primarily necessitated by MSVC++'s incompatibility with
declaring std::swap<Use> to be a friend of Use.
Also contains some minor tweaks to Use inline functions,
to undo pointless changes that sneaked in with the last merge.
