73ea7bf450 Add the SubRegIndex TableGen class. 
This is the beginning of purely symbolic subregister indices, but we need a bit
of jiggling before the explicit numeric indices can be completely removed.

af1465b17b add the ability to associate 'category' names with clang diagnostics 
and diagnostic groups.  This allows the compiler to group 
diagnostics together (e.g. "Logic Warning", 
"Format String Warning", etc) like the static analyzer does.  
This is not exposed through anything in the compiler yet.

b55c8bed9d Add a pseudo instruction REG_SEQUENCE that takes a list of registers and 
sub-register indices and outputs a single super register which is formed from
a consecutive sequence of registers.

This is used as register allocation / coalescing aid and it is useful to
represent instructions that output register pairs / quads. For example,
v1024, v1025 = vload <address>
where v1024 and v1025 forms a register pair.

This really should be modelled as
v1024<3>, v1025<4> = vload <address>
but it would violate SSA property before register allocation is done.

Currently we use insert_subreg to form the super register:
v1026 = implicit_def
v1027 - insert_subreg v1026, v1024, 3
v1028 = insert_subreg v1027, v1025, 4
...
      = use v1024
      = use v1028

But this adds pseudo live interval overlap between v1024 and v1025.

We can now modeled it as
v1024, v1025 = vload <address>
v1026 = REG_SEQUENCE v1024, 3, v1025, 4
...
      = use v1024
      = use v1026

After coalescing, it will be
v1026<3>, v1025<4> = vload <address>
...
      = use v1026<3>
      = use v1026

9899f70a74 Fixed a nasty layering violation in the edis source 
code.  It used to #include the enhanced disassembly
information for the targets it supported straight
out of lib/Target/{X86,ARM,...} but now it uses a
new interface provided by MCDisassembler, and (so
far) implemented by X86 and ARM.

Also removed hacky #define-controlled initialization
of targets in edis.  If clients only want edis to
initialize a limited set of targets, they can set
--enable-targets on the configure command line.

1808e4d251 If all the bit positions are not specified; do not decode the instructions. 
We are bound to fail!  For proper disassembly, the well-known encoding bits
of the instruction must be fully specified.

This also removes pseudo instructions from considerations of disassembly,
which is a better design and less fragile than the name matchings.
