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

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.

Remove some clutter and make it keep going instead of stopping at the
first difference.

Fix PR1057 (compilation on macos 10.3), patch by Scott Michel!

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@32644 91177308-0d34-0410-b5e6-96231b3b80d8

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

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.

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

Fixed so that it dereferences the ostream pointer.

Accidental submission.

This snuck in. Reverted.

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.

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.

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.

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.

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.
