ca1f1c58e1 Added support to write out ConstantExpr nodes.
Also, avoid asserting out when writing out an invalid tree
since the assembly writer is used when debugging.

d670638ee6 Added subclass ConstantExpr to represent expressions consructed from
constants using operators such as cast, getelementptr, add, shl, etc.
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.

155a8ec344 Write out the plane for types first, since values of primitive types
may be constructed by expressions of other types (and so the
contents of the primitive type planes must come after all types).
Use a helper function outputConstantsInPlane in outputConstants to
do this.

3df324e6e8 Major overhaul to stop using pseudo-instructions (SETX, SETUW, SETSW)
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.

9d7346bbf9 More important fixes:
-- 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.

a771830ea1 Have to save a boolean (setCC) value whenever use is outside the current
basic block.

Mark setCCInstr used as dest. of conditional-move as both a def and a use.

b94ede185c Significant changes to correctly spill CC registers and to correctly
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.
