f1e8e0a0cf Thoroughly rehack the dynamic linking mechanisms on Win32. The Win32 
dynamic linker does not automatically search libraries when looking up
symbols with GetProcAddress.  Because of this we have to emulate it.  The
only detail is that there doesn't seem to be a way to enumerate the
libraries loaded, so we have a gross hack (tm).

This make the JIT functional on win32 under cygwin.

a49f11bec4 Fix the big regression that has been killing the nightly tester these last 
few days.  Apparently the old symbol table used to auto rename collisions in
the type symbol table and the new one does not.  It doesn't really make sense
for the new one to do so, so we just make the client do it.

928f12aa15 Add support for getting executable memory on Windows. This is actually 
much easier than on unix.  :)  The only evil thing is that windows.h defines
a macro named FindExecutable, which collides with one of our names.

The JIT now runs on windows, but it cannot resolve external functions
(like printf) yet.

b2939fc651 Use the SymbolTable::isEmpty() method instead of checking for no value 
planes. A SymbolTable could still have types in it! This fixes problems
with two regression tests that failed because a symbol table that only
contained types was being omitted from bytecode files. Thanks to Chris
for the reduced test case that helped find this immediately.

736ca634a7 This code is a real mess, but at least get the JIT *building* on platforms 
(such as plan 9) without mmap.  Of course it won't RUN... but that's another
step.  :)

97bd391386 Fix InstCombine/load.ll & PR347. 
This code hadn't been updated after the "structs with more than 256 elements"
related changes to the GEP instruction.  Also it was not handling the
ConstantAggregateZero class.

Now it does!

e91dc2545c Restructure call constant folding code a bit to make it simpler 
Add support for acos/asin/atan.  188.ammp contains three calls to acos with
constant arguments.  Constant folding it allows elimination of those 3 calls
and three FP divisions of the results.

b7b1b9d4b2 Several clean ups suggested by Chris: remove tabs, make SlotMachine do lazy 
initialization so we don't scan large Modules/Functions needlessly, tighten
up restrictions on what can be put in SlotMachine (no Constants that aren't
GlobalValues).

9a0451787d Provide the correct patch for bug 345. The solution is to add a setTypeName 
function to llvmAsmParser.y and then use it in the one place in the grammar
that needs it. Also had to make Type::setName public because setTypeName
needs it in order to retain compatibility with setValueName.
