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.

llvm-svn: 2856

-- 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.

changes in class MachineRegInfo (see MachineRegInfo.h for details).

Added {LD,ST}[X]FSR instructions.

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.

llvm-svn: 2836

Added LDFSR, LDXFSR, STFSR and STXFSR.
Fixed operands info for RDCCR, WRCCR.

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.

Moved here from MachineInstr.cpp to make it an annotation on BasicBlock.

so additional dep. edges have to be added.
This was needed to correctly handle conditional move instructions!
MachineCodeForBasicBlock is now an annotation on BasicBlock.
Renamed "earliestForNode" to "earliestReadyTimeForNode".

An (explicit or implicit) operand may now be both a def and a use.
Also add a set of regs used by each instruction.
dump() no longer takes an optional argument, which doesn't work in gdb.
