004cce78e1 Resynchronize EDInfo.h and EDEmitter.cpp.
The enum names as well as order (i.e. value)
had skewed, which means that consumers of the
tablegen-ed table would see different values than
intended. Make both files have a superset of enums,
and add classification as needed for numMCOperands.

c9e252df68 Change createAsmParser to take a MCSubtargetInfo instead of triple,
CPU, and feature string. Parsing some asm directives can change
subtarget state (e.g. .code 16) and it must be reflected in other
modules (e.g. MCCodeEmitter). That is, the MCSubtargetInfo instance
must be shared.

50f2d8d304 Eliminate asm parser's dependency on TargetMachine:
- Each target asm parser now creates its own MCSubtatgetInfo (if needed).
- Changed AssemblerPredicate to take subtarget features which tablegen uses
  to generate asm matcher subtarget feature queries. e.g.
  "ModeThumb,FeatureThumb2" is translated to
  "(Bits & ModeThumb) != 0 && (Bits & FeatureThumb2) != 0".

034261674b Fix the ridiculous SubtargetFeatures API where it implicitly expects CPU name to
be the first encoded as the first feature. It then uses the CPU name to look up
features / scheduling itineray even though clients know full well the CPU name
being used to query these properties.

The fix is to just have the clients explictly pass the CPU name!

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.

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
were being sent to errs() because no error handler
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.

a2eec46242 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.

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>

1ac58ea0f3 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.
