Convert SetValue to take the value name as an Init. This allows us to
set values for variables whose names are not yet fully resolved.

Multidefs are a bit unwieldy and incomplete. Remove them in favor of
another mechanism, probably for loops.

Add parser support to recognize multidefs. No processing on the
multidef is done at this point. The grammar is:
MultiDef = MULTIDEF ObjectName < Value, Declaration, Value > ObjectBody
The first Value must be resolveable to a list and the second Value
must be resolveable to an integer. The Declaration is a temporary
value used as an iterator to refer to list items during processing.
It may be passed into the ObjectBody where it will be substituted with
the list value used to instantiate each def.
llvm-svn: 141232
Move the code to instantiate a multiclass def, bind its arguments and
resolve its members into three helper functions. These will be reused
to support a new kind of multiclass def: a multidef.
