Kevin Enderby 9377a52c12 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)

Sean Callanan 1426351c83 Redirected errors from the AsmParser to the proper
error stream, in cases where the AsmParser is
being invoked by EDDisassembler.  Before, they
were being sent to errs() because no error handler
was installed in the SourceMgr.

Sean Callanan 6c6be946fc Fixed a bug where missing EDInstInfo would cause
tokenization to crash and burn.

Shantonu Sen e59f8ca49e 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.

Kevin Enderby f3070dc40d 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.

Bill Wendling 00f0cddfd4 We need to pass the TargetMachine object to the InstPrinter if we are printing
the alias of an InstAlias instead of the thing being aliased. Because we need to
know the features that are valid for an InstAlias.

This is part of a work-in-progress.

Shantonu Sen fd3e83953f Fix comparator used for looking up previously instantiated EDDisassemblers.
Now, Syntax is only used as a tie-breaker if the Arch
matches. Previously, a request for x86_64 disassembler followed by the
i386 disassembler in a single process would return the cached x86_64
disassembler. Fixes <rdar://problem/8958982>

Chris Lattner 979634bbb0 start straightening out libedis's dependencies and make it fit
better in the llvm world.  Among other things, this changes:

1. The guts of libedis are now moved into lib/MC/MCDisassembler
2. llvm-mc now depends on lib/MC/MCDisassembler, not tools/edis,
   so edis and mc don't have to be built in series.
3. lib/MC/MCDisassembler no longer depends on the C api, the C
   API depends on it.
4. Various code cleanup changes. 

There is still a lot to be done to make edis fit with the llvm
design, but this is an incremental step in the right direction.
