First step in refactoring the SymbolTable is to split it into two classes,
one for a symbol table of types and one for a symbol table of Values.

This fixes a "gccass" regression. The -debug-pass=Structure option now
prints all the appropriate output

"added the asserts and casts, fixed the comments and started the break
down of the larger methods.  A few more patches and the breakdown
should be complete."

Fold:
seteq ({ short }* cast (int 1 to { short }*), { short }* null)
setlt ({ short }* cast (int 1 to { short }*), { short }* cast (int 2 to { short }*))

to false/true.  These last two commonly occur in the output of compilers that
tag integers, like cozmic's scheme compiler.

This sanitises the world, blows away the specialisations and adds
traits per passmanager type -- seemed most natural.

"All this should do is create what will eventually be the specialised
passmanagers.  Currently, the templates are inheriting them, once the
template specialisations' methods have been absorbed, patches
submitted method by method.  I'll nuke the specialisations and have
the new objects inherit directly from passmanagert, and sanitise the
world of all references to templates.

Implement the suggested check to ensure that out-of-range float constants
don't get accepted by LLVM accidentally. Adjust the supporting test cases
as well.

* Fix several issues in TypeMap::RefineAbstractType that prevent it from
  handling hash values that change correctly.
* Define hashTypeStructure to not always return 0.  :)

This last part (which depends on the first two) speeds up gccld time on eon
from 3.78s to 2.75s with a release build (a 28% speedup!).  This resolves

to letters and numbers as symbol names.  If you don't want this, use
markCharUnacceptable to remove one of these or markCharAcceptable to add
to the set.  This corresponds with what GAS accepts by default.

Also, this includes some minor speedups
