68f28730b7 Revert elimination of global variable hack... still needed.

2cf40e142c Eliminate the use of the global variable hack in the X86 target that was used 
to get Visual Studio to link in X86.lib to the executables that need it.  There
is another way of doing it.

23c8d0b65a The person who was planning to add SSE support isn't anymore, so disable 
the -sse* options (to avoid misleading people).

Also, the stack alignment of the target doesn't depend on whether SSE is
eventually implemented, so remove a comment.

7c16caa336 Changes For Bug 352 
Move include/Config and include/Support into include/llvm/Config,
include/llvm/ADT and include/llvm/Support. From here on out, all LLVM
public header files must be under include/llvm/.

e6e1b48023 I believe that the code generator now properly handles dead basic blocks. If not, 
this is a bug, and should be fixed.

80da865f77 Change MachineBasicBlock's vector of MachineInstr pointers into an 
ilist of MachineInstr objects. This allows constant time removal and
insertion of MachineInstr instances from anywhere in each
MachineBasicBlock. It also allows for constant time splicing of
MachineInstrs into or out of MachineBasicBlocks.

68cff6bf4d Remove floating point killer pass. This is now implemented in the 
instruction selector by adding a new pseudo-instruction
FP_REG_KILL. This instruction implicitly defines all x86 fp registers
and is a terminator so that passes which add machine code at the end
of basic blocks (like phi elimination) do not add instructions between
it and the branch or return instruction.

452597611f Finally, _actually delete the machine code_ for a function, after it has 
been emitted.  Also, since the FPK pass is causing memory access violations,
disable it.

904cd6d48c Add a floating point killer pass. This pass runs before register 
allocaton on the X86 to add information to the machine code denoting
that our floating point stackifier cannot handle virtual point
register that are alive across basic blocks. This pass adds an
implicit def of all virtual floating point register at the end of each
basic block.

6d760d7cb3 Add an option to enable the SSA based peephole optimizer. 
Eventually this pass will provide substantially better code in the interim between when we
have a crappy isel and nice isel.  Unfortunately doing so requires fixing the backend to
actually SUPPORT all of the fancy addressing modes that we now generate, and writing a DCE
pass for machine code.  Each of these is a fairly substantial job, so this will remain disabled
for the immediate future.  :(
