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.

re-factor the AutoUpgrade implementation to eliminate some duplication of
code.

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).

"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.

"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.

type when it gets refined. This allows us to hash on this crucial value.
* 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
PR474.

names. This also changes the default to allow all of "$_." in addition
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

Do not mangle internal global names that do not collide with anything.
This gives us strings that now look like this:
__2E_str_1: ; '.str_1'
.asciz "foo"
instead of this:
l1__2E_str_1: ; '.str_1'
.asciz "foo"

Add support for specifying alignment and size of setjmp jmpbufs.
No targets currently do anything with this information, nor is it presrved
in the bytecode representation. That's coming up next.

When moving constant entries in 'Map' if the entry is the representative
constant for the abstractypemap, make sure to update it as well. This
fixes the bcreader failures from last night on several C++ apps.
llvm-svn: 23628
creating the keys and doing comparisons to index into 'Map' takes a lot
of time. For these large constants, keep an inverse map so that 'remove'
and move operations are much faster.
This speeds up a release build of the bc reader on Eric's nasty python
bytecode file from 1:39 to 1:00s.

constant arrays in place instead of reallocating them and replaceAllUsesOf'ing
the result. This speeds up a release build of the bcreader from:
136.987u 120.866s 4:24.38
to
49.790u 49.890s 1:40.14
... a 2.6x speedup parsing a large python bc file.

This speeds up isa/dyncast/etc for constants, and also makes them smaller.
For example, the text section of a release build of InstCombine.cpp shrinks
from 230037 bytes to 216363 bytes, a 6% reduction.
