8229bc7c80 If we know that it's a constant being casted, propagate through the cast 
instruction. Doesn't work the other way though (can't recover bits that
have been truncated).

a pass manager for itself.

There is some opportunity to remove some dead code from PassManager.cpp.

d6ed2499db Back out the last patch which is a nightly test killer. The assertion 
in getLocalSlot fires on many, many values. It broke nearly all of
the dejagnu tests. Simple changes to the assertion did not fix the
problem.

b4f3c47095 For PR1099: 
Invert the "isSigned" logic in calls to printType and printPrimitiveType.
We want variables to be declared unsigned by default so that signless
operators like + and - perform the unsigned operation that LLVM expects
by default. Parameters with the sext attribute will be declared signed and
signed instructions will case operand values to signed regardless of the
type of the variable. This passes all tests and fixes PR1099.

76d79c7040 For PR1099: 
Partial fix for this PR. Default function parameters to signed integer, just
like everything else in CBE. The bug was caused by incorrectly introducing
parameter attributes feature by choosing "signed" parameter if the
SExtAttribute was specified. Howeer, if no attribute is specified, this
causes it to become unsigned which is incorrect. Reversing the logic so
that signedness is detected by "not ZExtAttribute" set fixes the issue.

This fixes 197.parser but there is more to do. Any comparison and possibly
other operators involving arguments may need to correctly cast the parameter
before its use, depending on the sign of the operator.
