current PC.  rdar://7834775

assembler for something like this:

        jmp L1
        .long . - L0
L1:

5894c0b60e While DAE can't modify the function signature of an externally visible function, 
it can check whether the visible direct callers are passing in parameters to
dead arguments and replace those with undef.

This reinstates r94322 with bugs fixed.

6f72ab345d Fixed another assert exposed by fuzzing. Now, when an encoding error occurs 
involing getBFCInvMask() where lsb <= msb does not hold true, the disassembler
just returns false, instead of assert, to indicate disassembly error.

9899f70a74 Fixed a nasty layering violation in the edis source 
code.  It used to #include the enhanced disassembly
information for the targets it supported straight
out of lib/Target/{X86,ARM,...} but now it uses a
new interface provided by MCDisassembler, and (so
far) implemented by X86 and ARM.

Also removed hacky #define-controlled initialization
of targets in edis.  If clients only want edis to
initialize a limited set of targets, they can set
--enable-targets on the configure command line.
