b985158c35 Make debugging output with -print-machineinstrs more useful: always print out
the transformed LLVM code which is the input to the instruction selector.

9d1af97d02 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.

49f61c4ea4 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.

6ed81e253c 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.

75719bf239 Provide the correct patch for bug 345. The solution is to add a setTypeName

needs it in order to retain compatibility with setValueName.

798ff64328 Part of bug 122:
This change removes the BuildBytecodeInfo flag from the SlotCalculator
class. This flag was needed to distinguish between the Bytecode/Writer
and the AsmWriter. Now that AsmWriter doesn't use SlotCalculator, we can
remove this flag and simplify some code. Also, some minor name changes
to CachedWriter.h needed to be committed (missed in previous commit).

change passes all Feature and Regression tests.

293a55f9f0 Adding the initial implementation of the SlotTable class. This class is
the Abstract Data Type that holds slot number values and associates them
with Type* and Value*. The SlotTable is simply the holder of the slot
numbers and provides a controlled interface for building the table. It does
not enforce any particular idiom or functionality for manipulating the slot
numbers.

This is part of bug_122. The SlotCalculator and SlotMachine classes will
follow.

3c6a0d4ae2 Implement InstCombine:shift.ll:test16, which turns (X >> C1) & C2 != C3
into (X & (C2 << C1)) != (C3 << C1), where the shift may be either left or
right and the compare may be any one.

This triggers 1546 times in 176.gcc alone, as it is a common pattern that
occurs for bitfield accesses.

c5204fb6f8 Complete rewrite of the code that merges DS graphs for equivalence classes
of functions called at a common call site.  The rewrite inlines the
resulting graphs bottom-up on the SCCs of the CBU call graph.  It also
simplifies the merging of equivalence classes by exploiting the fact that
functions in non-trivial SCCs are already merged.
