a2da78852b Fix infinite loop in nested multiclasses.
Patch by Michael Liao!

c78bd9ba6b Switch the TableGen record's string-based DenseMap key to use the new
hashing infrastructure. I wonder why we don't just use StringMap here,
and I may revisit the issue if I have time, but for now I'm just trying
to consolidate.

cebb4ee93a Add Foreach Loop
Add some data structures to represent for loops.  These will be
referenced during object processing to do any needed iteration and
instantiation.

Add foreach keyword support to the lexer.

Add a mode to indicate that we're parsing a foreach loop.  This allows
the value parser to early-out when processing the foreach value list.

Add a routine to parse foreach iteration declarations.  This is
separate from ParseDeclaration because the type of the named value
(the iterator) doesn't match the type of the initializer value (the
value list).  It also needs to add two values to the foreach record:
the iterator and the value list.

Add parsing support for foreach.

Add the code to process foreach loops and create defs based
on iterator values.

Allow foreach loops to be matched at the top level.

When parsing an IDValue check if it is a foreach loop iterator for one
of the active loops.  If so, return a VarInit for it.

Add Emacs keyword support for foreach.

Add VIM keyword support for foreach.

Add tests to check foreach operation.

Add TableGen documentation for foreach.

Support foreach with multiple objects.

Support non-braced foreach body with one object.

Do not require types for the foreach declaration.  Assume the iterator
type from the iteration list element type.

7aef99b677 ARM vldm and vstm VFP instructions can take a data type suffix.
It's ignored by the assembler when present, but is legal syntax. Other
instructions have something similar, but for some mnemonics it's
only sometimes not significant, so this quick check in the parser will
need refactored into something more robust soon-ish. This gets some
basics working in the meantime.

d3d1cad535 Implement Paste
Add a paste operator '#' to take two identifier-like strings and joint
them.  Internally paste gets represented as a !strconcat() with any
necessary casts to string added.

This will be used to implement basic for loop functionality as in:

for i = [0, 1, 2, 3, 4, 5, 6, 7] {
  def R#i : Register<...>
}

f3744a0cf9 Make ID Parsing More Flexible
Add a mode control to value and ID parsers.  The two modes are:

- Parse a value.  Expect the parsed ID to map to an existing object.

- Parse a name.  Expect the parsed ID to not map to any existing object.

The first is used when parsing an identifier to be looked up, for
example a record field or template argument.  The second is used for
parsing declarations.  Paste functionality implies that declarations
can contain arbitrary expressions so we need to be able to call into
the general value parser to parse declarations with paste operators.
So we need a way to parse a value-like thing without expecting that
the result will map to some existing object.  This parse mode provides
that.

a761f92cd3 Add Peek
Add a peek function to let the Lexer look at a character arbitrarily
far ahead in the stream without consuming anything.  We need this to
disambiguate numbers and operands of a paste operation.  For example:

def foo#8i

Without lookahead the lexer will treat '8' as a number rather than as
part of a string to be pasted to form an identifier.

f628204262 Allow Names Changes on Unregistered Records
Add Record names to be changed even on Records that aren't yet

because we do not want to register def names before they are unique
and that can only happen once all paste operations are done.  This
change lets us update Record names formed by paste operations and
register the result later.

caa25c81cd Prefix Template Arg Names with Multiclass Name
For consistency, prefix multiclass template arg names with the
multiclass name followed by "::" to avoid name clashes among
multiclass arguments and other entities in the multiclass.

a6d442e651 Process Multidefs
Process each multidef declared in a multiclass.  Iterate through the
list and instantiate a def in the multiclass for each item, resolving
the list item to the temporary iterator (possibly) used in the
multidef ObjectBody.  We then process each generated def in the normal
way.

6da674cda1 Parser Multidef Support
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.

e499a2df44 Refactor Multiclass Def Processing
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.

cedaae125e Allow Operator Arguments
When resolving an operator list element reference, resolve all
operator operands and try to fold the operator first.  This allows the
operator to collapse to a list which may then be indexed.

Before, it was not possible to do this:
class D<int a, int b> { ... }
class C<list<int> A> : D<A[0], A[1]>;
class B<list<int> b> : C<!foreach(...,b)>;

Now it is.

f987425657 tblgen: add preprocessor as a separate mode
This patch adds a preprocessor that can expand nested for-loops for
saving some copy-n-paste in *.td files.

The preprocessor is not yet integrated with TGParser, and so it has
no direct effect on *.td inputs.  However, you may preprocess an td
input (and only preprocess it).

To test the proprecessor, type:
  tblgen -E -o $@ $<
