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.

- Fixed bugs in sethi-ullman number computation and priority queue comparison
functions.
- Separate code that handles priority computation special cases from SU number computation.

Eventually, Top level pass managers will use this to keep track of
active pass managers. Eass pass will also learn how to find appropriate
manager from these managers stack.

This patch converts getPrimitiveSize to getPrimitiveSizeInBits where it is
appropriate to do so (comparison of integer primitive types).

Enable complex addressing modes on 64-bit platforms involving two induction
variables by keeping a size and scale in 64-bits not 32.

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.

Take an incremental step towards type plane elimination. This change
separates types from values in the symbol tables by finally making use
of the TypeSymbolTable class. This yields more natural interfaces for
dealing with types and unclutters the SymbolTable class.
