5532cf44a0 llvm-mc: Remove --show-fixups and always show as part of --show-encoding. 
Also, fix a silly memory leak.

2e235a826d Fixed the disassembler so it accepts multiple 
instructions on a single line.  Also made it a
bit more forgiving when it reports errors.

e73a31f667 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.

bf2013ee22 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.

79ed1a8734 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.

9898671a74 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.
