Remove all grammar conflicts from assembly parsing. This change involves:
1. Making the "type" keyword not a primitive type (removes several
reduce/reduce conflicts)
2. Being more specific about which linkage types are allowed for functions
and global variables. In particular "appending" can no longer be
specified for a function. A differentiation was made between the various
internal and external linkage types.
3. Introduced the "define" keyword which is now required when defining a
function. This disambiguates several cases where a named function return
type could get confused with the definition of a new type. Using the
keyword eliminates all shift/reduce conflicts and the remaining
reduce/reduce conflicts.
These changes are necessary to implement the function parameter attributes
that will be introduced soon. Adding the function parameter attributes in
the presence of the shift/reduce and reduce/reduce conflicts led to severe
ambiguities that caused the parser to report syntax errors that needed to
be resolved. This patch resolves them.

1. Make the arguments const like the other ConstantFold* functions.
2. Clean up evaluateFCmpRelation so it makes sense for floating point.
3. Implement the use of evaluateFCmpRelation to fold floating point CEs
4. Shorten a variable name so more things fit on one line.
5. Fix various comments.

This patch removes the SetCC instructions and replaces them with the ICmp
and FCmp instructions. The SetCondInst instruction has been removed and
been replaced with ICmpInst and FCmpInst.

pass managers. Otherwise, stale available analysis info, from the managers not
yet run, may cause pass manager to take wrong turn.
This fixes CBE test failures reported by nightly tester.

values regardless of the signedness of the constant's type, it is okay to
always make the AsmWriter.cpp print constant ints as signed values. The
AsmParser will automatically handle things like: uint -1 as a result.

Introduce FPPassManager to manage function passes and
BBPassManagers.
Now FunctionPassManagerImpl is an implementation class
used by externally visible FunctionPassManager to manage
FPPassManagers.
Module pass manager (MPPassManager) now manages FPPassManagers
and ModulePasses.

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.

Register pass has the its last user, otherwise sometimes no one will claim
LastUse.
Handle transferred last uses from child pass manager.
