0139e2193d Fixed the disassembler so it accepts multiple
instructions on a single line.  Also made it a
bit more forgiving when it reports errors.

276811b58a Stop building RTTI information for *most* llvm libraries. Notable
missing ones are libsupport, libsystem and libvmcore.  libvmcore is
currently blocked on bugpoint, which uses EH.  Once it stops using
EH, we can switch it off.

This #if 0's out 3 unit tests, because gtest requires RTTI information.
Suggestions welcome on how to fix this.

e9111e7172 Moved handling of inclusion from the AsmLexer to
the AsmParser, breaking AsmLexer's dependence on
SourceMgr.

52633cb655 Changed the AsmParser to handle error messages itself
rather than passing them off to the AsmLexer to handle.
This means the AsmLexer no longer requires a SourceMgr
to do error handling.

the two token accessor functions are declared consistently.

985ff03e7d Added a Lex function to the AsmParser, to allow handling
of include directives to occur within the parser itself.
This will break the lexer's dependency on a SourceMgr as
input.

882cb240a6 Split the TargetAsmParser "ParseInstruction" interface in half:
the new ParseInstruction method just parses and returns a list of
target operands.  A new MatchInstruction interface is used to
turn the operand list into an MCInst.

This requires new/deleting all the operands, but it also gives 
targets the ability to use polymorphic operands if they want to.

023fdbe1b6 Test harness for the LLVM disassembler. When invoked
with -disassemble, llvm-mc now accepts lines of the
form
0x00 0x00
and passes the resulting bytes to the disassembler for
the chosen (or default) target, printing the result.
