c8da528e6c Split memcpy/memset/memmove intrinsics into i32/i64 versions, resolving 
PR709, and paving the way for future progress.

Significantly refactor autoupgrading code, to handle the more complex case
(where we upgrade one argument in a function), and fix some bugs in it.

Testcase here: llvm/test/Regression/Bytecode/memcpy.ll

ff2ce95673 Speedup and simplify pass registration by the observation that there is 
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.

3cecd3c4cf For PR411: 
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.

ea1bec59db For PR411:

much easier to understand.

doubtful."

ee327e57d2 Implement a few symbolic constant folding things. X ? Y : Y is Y. 
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.

a04fb40243 Patch #1 of Saem Ghani's Pass Manager refactoring. From the man: 
"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.

b98aa6cc83 refactor a bit of code. 
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.

8cce7373f7 For large constants (e.g. arrays and structs with many elements) just 
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.

eb44192fe0 Change ConstantArray::replaceUsesOfWithOnConstant to attempt to update 
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.

20786460b5 Split SimpleConstantVal up into its components, so each Constant subclass getsa different enum value. This allows 'classof' for these to be really simple,not needing to call getType() anymore. 
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.

4a3dc26192 Now that hasConstantValue is more careful w.r.t. returning values that only 
dominate the PHI node, this code can go away.  This also makes passes more
