f31673d965 Convert the last use of two-argument ConstantExpr::getCast into another 
form so we can remove that method from ConstantExpr.

503ae10c88 Add a couple little tests for SExt/ZExt of constants of a sign that doesn't 
match.

9ac4a6b7d0 Remove the last use of getUnsignedVersion and getSignedVersion from VMCore. 
ConstantInt doesn't care about the sign of the type it represents. It only
cares about the bitwidth so there is no need to make the sign of the type
match the SExt or ZExt constant expression.

0cb59889d2 Use a predicate function to identify bitcast of fp and integer instead of 
repeating the logic in two different parts of the code.

85f67cbc7a Fix PR1058: 
Generate the BITCAST_TEMPORARY regardless of the uses or inlinability of
the instruction. This temporary is needed to perform the instruction, not
provide storage for its results.

10d7a4b963 Added example of how to code print() methods so that they will disappear 
from the code if "cnull" is passed into them.

be18cd1575 Fix problems in the CBE and InstructionCombining which use the isMaxValue 
and isMinValue methods of ConstantInt. These have been broken since the
isSigned parameter was added. It is necessary to use the signed version
of the type in the call to isValueValidForType or else incorrect results
are returned.

7f6a73eb5c Added an automatic cast to "std::ostream*" etc. from OStream. We then can 
rework the hacks that had us passing OStream in. We pass in std::ostream*
instead, check for null, and then dispatch to the correct print() method.

758736b8df Allow an --enable-pic option to turn on -fPIC compiler option when building. 
The default is disabled until we know this doesn't break anyone.

6bdae11796 when inserting a dummy argument to work-around the CBE not supporting 
zero arg vararg functions, pass undef instead of 'int 0', which is cheaper.

8b1e4d1edf Fix PR1049 and CodeGen/Generic/2006-12-16-InlineAsmCrash.ll 
by producing target constants instead of constants.  Constants can get
selected to li/movri instructions, which causes the scheduler to explode.
