4ef51373c4 Use intrinsic lowering like the rest of the backends. Get rid of crufty hacky 
code that worked around problems in the mangler

f31182a531 Convert the C backend into a target, for use with LLC. This allows us to use 
the lowerallocations pass to eliminate malloc/free warnings and hackish code

94f4f8ea10 Make the cwriter use the lowerinvoke pass so that it can either use "disabled exceptions" or 
"expensive exceptions" controlled by an option.  Also refactor and eliminate a bunch of cruft.
This is a temporary solution and causes millions of warnings to pour out of programs that use
exceptions, but it should fix the problem with sparc and the 'write' declaration (PR190).
Subsequent changes will make this stink much less

c0b9dc5be7 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.

MO_VirtualRegister but if the register number is one of a physical
register is it considered as a physical register.
