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.

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.

Eventually, Top level pass managers  will use this to keep track of

This patch converts getPrimitiveSize to getPrimitiveSizeInBits where it is

Clean up the definitions of the helper functions per Chris' review
suggestions so they are easier to read.

For PR1091:
Print minimum signed integer values as unsigned so that we get no warnings
from the C compiler about constant ranges and value comparisons.

Implemented some llvm_fcmp_{pred} functions at the start of the function bodies
and use them for fcmp instructions and constant expressions. These help
implement the ordered and unordered comparisons necessary for correct exectuion
of these comparisons.
