This may be used as the second IRBuilder template
parameter, the idea being that people learning LLVM
may find it helpful (several people asked on IRC
if it was possible to turn off constant folding
because it made it hard for them to see what was
going on).  Compiles, but otherwise completely
untested.

relevant test. This helps it avoid using MAX expressions in
loop trip counts in more cases.

addressing modes PC-relative.  Incomplete.

The assertion at the top of Emitter::runOnMachineFunction
was obviously bogus (always true) so I removed it.
If someone knows what the correct test should be to cover
all the various targets, please fix.

folding policies with IRBuilder.  The default,
provided by ConstantFolder, is to do minimal
folding like now: what ConstantExpr provides.
An alternative is to use TargetFolder, which
uses target information to fold constants more.
