c550ce0d48 Made the MC disassembler check before accessing 
MCInst operands for ARM.  This allows it to be
more tolerant of malformed MCInsts or incorrect
instruction metadata.

9009047cff malloc elimination: it's a bad idea to use raw_svector_ostream on a 
small heap-allocated SmallString because it unconditionally forces a malloc.

(Revised version of r129688, with the necessary flush() call.)

b653bac7ce To avoid printing out multiple error messages for cases like: 
.long 80+08

go ahead and assume that if we've got an Error token that we handled it
already. Otherwise if it's a token we can't handle then go ahead and
return the default error.

6e09a5d065 Adding support for printing operands symbolically to llvm's public 'C' 
disassembler API.  Hooked this up to the ARM target so such tools as Darwin's
otool(1) can now print things like branch targets for example this:
  blx _puts
instead of this:
  blx #-36
And even print the expression encoded in the Mach-O relocation entried for
things like this:
  movt r0, :upper16:((_foo-_bar)+1234)

0c1aa958e2 Redirected errors from the AsmParser to the proper 
error stream, in cases where the AsmParser is
being invoked by EDDisassembler.  Before, they

was installed in the SourceMgr.

a1467abb18 An MCDisassembler has the option to not implement 
getEDInfo(), in which case this code would dereference
NULL. EDInst can already handle NULL info, so avoid
the dereference and pass NULL through.

8c488cb152 Again adding a C API to the disassembler for use by such tools as Darwin's 
otool(1), this time with the needed fix for case sensitive file systems :) .
This is a work in progress as the interface for producing symbolic operands is
not done.  But a hacked prototype using information from the object file's
relocation entiries and replacing immediate operands with MCExpr's has been
shown to work with no changes to the instrucion printer.  These APIs will be
moved into a dynamic library at some point.
