* Add code to reduce multiplies by constant integers to shifts, adds and
subtracts. This is a very rough and nasty implementation of Lefevre's
"pattern finding" algorithm. With a few small changes though, it should
end up beating most other methods in common use, regardless of the size
of the constant (currently, it's often one or two shifts worse)
TODO: rewrite it so it's not hideously ugly (this is a translation from
perl, which doesn't help ;)
bypass most of it for multiplies by 2^n+1
(eventually) teach it that some combinations of shift+add are
cheaper than others (e.g. shladd on ia64, scaled adds on alpha)
get it to try multiple booth encodings in search of the cheapest
routine
make it work for negative constants
This is hacked up as a DAG->DAG transform, so once I clean it up I hope
it'll be pulled out of here and put somewhere else. The only thing backends
should really have to worry about for now is where to draw the line
between using this code vs. going ahead and doing an integer multiply
anyway.

Incorporate feedback from Chris:
* Change signatures of OptimizeCall and ValidateCalledFunction so they are
non-const, allowing the optimization object to be modified. This is in
support of caching things used across multiple calls.
* Provide two functions for constructing and caching function types
* Modify the StrCatOptimization to cache Function objects for strlen and
llvm.memcpy so it doesn't regenerate them on each call site. Make sure
these are invalidated each time we start the pass.
* Handle both a GEP Instruction and a GEP ConstantExpr
* Add additional checks to make sure we really are dealing with an arary of
sbyte and that all the element initializers are ConstantInt or
ConstantExpr that reduce to ConstantInt.
* Make sure the GlobalVariable is constant!
* Don't use ConstantArray::getString as it can fail and it doesn't give us
the right thing. We must check for null bytes in the middle of the array.
* Use llvm.memcpy instead of memcpy so we can factor alignment into it.
* Don't use void* types in signatures, replace with sbyte* instead.

Changes due to code review and new implementation:
* Don't use std::string for the function names, const char* will suffice
* Allow each CallOptimizer to validate the function signature before
doing anything
* Repeatedly loop over the functions until an iteration produces
no more optimizations. This allows one optimization to insert a
call that is optimized by another optimization.
* Implement the ConstantArray portion of the StrCatOptimization
* Provide a template for the MemCpyOptimization
* Make ExitInMainOptimization split the block, not delete everything

Post-Review Cleanup:
* Fix comments at top of file
* Change algorithm for running the call optimizations from n*n to something
closer to n.
* Use a hash_map to store and lookup the optimizations since there will
eventually (or potentially) be a large number of them. This gets lookup
based on the name of the function to O(1). Each CallOptimizer now has a
std::string member named func_name that tracks the name of the function
that it applies to. It is this string that is entered into the hash_map
for fast comparison against the function names encountered in the module.
* Cleanup some style issues pertaining to iterator invalidation
* Don't pass the Function pointer to the OptimizeCall function because if
the optimization needs it, it can get it from the CallInst passed in.
* Add the skeleton for a new CallOptimizer, StrCatOptimizer which will
eventually replace strcat's of constant strings with direct copies.

Make the CBackend actually get included in llc by using USEDLIBS instead of
USEDLIB as the variable to which "CBackend" is appended. The surrounding
if clause is safe because currently the configure script ensures that the
CBackend target is always added to TARGETS_TO_BUILD. By using a non-hard
coded construct in the makefile, we gain uniformity and the ability to
change the default set of targets by only changing the configure script.

First step in avoiding compilation/usage of non-relevant targets. New
options have been added to the configure script that control which targets
will be used. The options are:
--enable-target-this (default=disabled)
This will specify that the target corresponding to the build host is
the target that will be compiled/used. You can't use this with any of
the other options (they'll be ignored). This is what most people want.
--disable-target-x86 (default=enabled)
This will prevent the X86 target(s) from being compiled/used.
--disable-target-sparc (default=enabled)
This will prevent both SparcV8 and SparcV9 from being compiled/used.
--disable-target-powerpc (default=enabled)
This will prevent the PowerPC target from being compiled/used.
--disable-target-alpha (default=enabled)
This will prevent the Alpha target from being compiled/used.
--disable-target-ia64 (default=enabled)
This will prevent the IA64 target from being compiled/used.
Note that without any of these options, the default behavior is to build
all targets, as is the current practice.
All these options do is set up the substititution variable TARGETS_TO_BUILD
which contains the targets that should be compiled/used. The variable is
intended to be used in the makefiles. Those changes will come later.
