fade2f72b8 [TableGen] Change a couple methods to return an ArrayRef instead of a const std::vector reference. NFC

1405564987 [TableGen] Restore the use of the TheInit field in Record to cache the Record's DefInit. I broke this when I fixed memory leaks recently. Remove the DenseMap that mapped Record's to DefInit.

Apparently, the style needs to be agreed upon first.

be43b88fae [TableGen] Merge RecTy::typeIsConvertibleTo and RecTy::baseClassOf. NFC 
typeIsConvertibleTo was just calling baseClassOf(this) on the argument passed to it, but there weren't different signatures for baseClassOf so passing 'this' didn't really do anything interesting. typeIsConvertibleTo could have just been a non-virtual method in RecTy. But since that would be kind of a silly method, I instead re-distributed the logic from baseClassOf into typeIsConvertibleTo.

7fa3dea12d Remove StringRef->std::string->StringRef conversions. 
As StringInit::get() accepts StringRef there is no need 
to construct a std::string out of the StringRef input and
then construct a new StringRef from the std::string.

763d8b2ef7 [TableGen] Fully resolve class-instance values before defs in multiclasses 
By class-instance values I mean 'Class<Arg>' in 'Class<Arg>.Field' or in
'Other<Class<Arg>>' (syntactically s SimpleValue).  This is to differentiate
from unnamed/anonymous record definitions (syntactically an ObjectBody) which
are not affected by this change.

Consider the testcase:

    class Struct<int i> {
      int I = !shl(i, 1);
      int J = !shl(I, 1);
    }

    class Class<Struct s> {
        int Class_J = s.J;
    }

    multiclass MultiClass<int i> {
      def Def : Class<Struct<i>>;
    }

    defm Defm : MultiClass<2>;

Before this fix, DefmDef.Class_J yields !shl(I, 1) instead of 8.

This is the sequence of events.  We start with this:

    multiclass MultiClass<int i> {
      def Def : Class<Struct<i>>;
    }

During ParseDef the anonymous object for the class-instance value is created:

    multiclass Multiclass<int i> {
      def anonymous_0 : Struct<i>;

      def Def : Class<NAME#anonymous_0>;
    }

Then class Struct<i> is added to anonymous_0.  Also Class<NAME#anonymous_0> is
added to Def:

    multiclass Multiclass<int i> {
      def anonymous_0 {
        int I = !shl(i, 1);
        int J = !shl(I, 1);
      }

      def Def {
        int Class_J = NAME#anonymous_0.J;
      }
    }

So far so good but then we move on to instantiating this in the defm
by substituting the template arg 'i'.

This is how the anonymous prototype looks after fully instantiating.

    defm Defm = {
      def Defmanonymous_0 {
         int I = 4;
         int J = !shl(I, 1);
      }

Note that we only resolved the reference to the template arg.  The
non-template-arg reference in 'J' has not been resolved yet.

Then we go on to instantiating the Def prototype:

      def DefmDef {
         int Class_J = NAME#anonymous_0.J;
      }

Which is resolved to Defmanonymous_0.J and then to !shl(I, 1).

When we fully resolve each record in a defm, Defmanonymous_0.J does get set
to 8 but that's too late for its use.

The patch adds a new attribute to the Record class that indicates that this
def is actually a class-instance value that may be *used* by other defs in a
multiclass.  (This is unlike regular defs which don't reference each other and
thus can be resolved indepedently.)  They are then fully resolved before the
other defs while the multiclass is instantiated.

I added vg_leak to the new test.  I am not sure if this is necessary but I
don't think I have a way to test it.  I can also check in without the XFAIL
and let the bots test this part.

Also tested that X86.td.expanded and AAarch64.td.expanded were unchange before
and after this change.  (This issue triggering this problem is a WIP patch.)

d52b1d08df TableGen: delete no-op code 
This does nothing but remove the Record from the map, and
then re-add it, without actually changing it in between.

The Record's Name used to be changed before re-adding it
when the code was first committed in r137232, but the
name-changing lines were removed in r142510, and since
then this code seems to do nothing.

This was also the only caller of removeClass or removeDef,
so now RecordKeeper owns its Records unconditionally,
and could be unique_ptr-ified.

2093e2cb43 Change BitsInit to inherit from TypedInit. 
This is useful in a later patch where binary literals such as 0b000 will become BitsInit values instead of IntInit values.

d80222a48b [tablegen] Add !listconcat operator with the similar semantics as !strconcat 
Summary:
It concatenates two or more lists. In addition to the !strconcat semantics
the lists must have the same element type.

My overall aim is to make it easy to append to Instruction.Predicates
rather than override it. This can be done by concatenating lists passed as
arguments, or by concatenating lists passed in additional fields.

c09324483c Fix broken asserts that never fire. 
Change assert("text") to assert(0 && "text").  The first case is a const char *
to bool conversion, which always evaluates to true, never triggering the
assert.  The second case will always trigger the assert.
