Each DSGraph now keeps a list of pending callers that have not
been inlined into the function represented by that graph.
It also keeps a copy of the original call nodes before the BU pass
eliminates some of them.

- I->use_empty() can never be true because of the IHolder's
* Fix bug: test/Regression/Transforms/LevelRaise/2002-07-16-SourceAndDestCrash.ll
- Add a new NewCasts member to VMC to keep track of casts that have been
created and to ensure there is always a reference to the cast.
- Extend ValueHandle a bit so it can be used in an STL container
- Make sure we destroy the ValueMapCache before verifying the function
in LevelRaise.cpp

Also, avoid asserting out when writing out an invalid tree
since the assembly writer is used when debugging.

Note that a ConstantExpr can be of any type, so classof() in most
other subclasses (that discriminate by type) have to check that it
is also not a ConstantExpr.

contents of the primitive type planes must come after all types).
Use a helper function outputConstantsInPlane in outputConstants to
do this.

and generate actual machine instruction sequences directly.
Also a couple of bug fixes in code for putting constants into registers:
-- Do *not* sign-extend unsigned constant that is shorter than int reg size
-- Fix handling of address constant (a GlobalValue) vs. constant that
must be loaded.

-- FP argument to a function with no prototype going on stack
was not being copied to the stack in colorCallArgs().
-- Put caller-saving code *before* argument copying code so that
we don't trash a register before saving it!
-- Two other minor fixes.

basic block.
Mark setCCInstr used as dest. of conditional-move as both a def and a use.
BA instruction no longer has the unused CC argument.

handle conditional move instructions:
-- cpMem<->Reg functions now support CC registers (int and FP) correctly.
Also, cpMem<->Reg functions now return a vector of machine instructions.
-- Scratch registers must be explicitly provided to cpMem<->Reg when
needed, since CC regs need one to be copied to/from memory.
-- CC regs are saved to a scratch register instead of stack.
-- All regs used by a instruction are now recorded in MachineInstr::regsUsed,
since regs used to save values *across* an instruction are not obvious
either from the operands or from the LiveVar sets.
-- An (explicit or implicit) operand may now be both a def and a use.
This is needed for conditional move operations.
So an operand may need spill code both before and after the instruction.
Other changes:
-- Added several get{Class,Type} functions.
-- Added unified-to-local register number conversion.
-- class MachineCodeForBasicBlock is now an annotation on BasicBlock.
-- Suggest/Color methods may modify the MachineInstr (and always did),
so don't make that argument const!
-- Caller-saving code doesn't need its special purpose code for
handling CC registers since cpMem<->Reg handle those correctly now.
