No functionality changes, just improve the code by a) providing better
function names, b) eliminating a call to get_suffix and c) tightening up
a function elimination test to reduce further checking.

exactly one PassInfo object per RegisterPass object and that their lifetimes
are the same.  As such, there is no reason for the RegisterPass object to
dynamically allocate the PassInfo object at compiler startup time: just inline
the object by-value.  This should reduce codesize, heap size, and startup time. Yaay.

This patch is an incremental step towards supporting a flat symbol table.
It de-overloads the intrinsic functions by providing type-specific intrinsics
and arranging for automatically upgrading from the old overloaded name to
the new non-overloaded name. Specifically:
  llvm.isunordered -> llvm.isunordered.f32, llvm.isunordered.f64
  llvm.sqrt -> llvm.sqrt.f32, llvm.sqrt.f64
  llvm.ctpop -> llvm.ctpop.i8, llvm.ctpop.i16, llvm.ctpop.i32, llvm.ctpop.i64
  llvm.ctlz -> llvm.ctlz.i8, llvm.ctlz.i16, llvm.ctlz.i32, llvm.ctlz.i64
  llvm.cttz -> llvm.cttz.i8, llvm.cttz.i16, llvm.cttz.i32, llvm.cttz.i64
New code should not use the overloaded intrinsic names. Warnings will be
emitted if they are used.

This file makes the helper functions for auto-upgrade of llvm assembly and
bytecode more accessible. This is part of de-overloading of intrinsic
functions to support the flat symbol table (no type planes).

"Extracts a few more methods, reduces some redundancy in the code at
the same time."

"Cut up the runPasses method into smaller pieces.  The small private
helpers should  be easier to deal with when code shuffling arising
from creating the new specialised batchers, not to mention, they're
much easier to understand.

I inlined them, in case function call overhead would be noticeable --
doubtful."

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.

"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.
