dd9b184c19 Change forward declaration of MultiClass to use the "struct" keyword instead 
of "class", so that it matches the subsequent definition.

a28b42f818 Fix multiclass inheritance to limit value resolution to new defs added 
by base multiclasses.  Do not attempt to alter defs from previous base
multiclasses.  This fixes multiple multiclass inheritance.

a92a50c7c2 Make BinOps typed and require a type specifier for !nameconcat. This 
allows binops to be used in typed contexts such as when passing
arguments to classes.

0eed59a7df Add support to tablegen for naming the nodes themselves, not just the operands, 
in selectiondag patterns.  This is required for the upcoming shuffle_vector rewrite,
and as it turns out, cleans up a hack in the Alpha instruction info.

7af521bd0c add a new TGError class and use it to propagate location info with 
errors when thrown.  This gets us nice errors like this from tblgen:

CMOVL32rr: 	(set GR32:i32:$dst, (X86cmov GR32:$src1, GR32:$src2))
/Users/sabre/llvm/Debug/bin/tblgen: error:
Included from X86.td:116:
Parsing X86InstrInfo.td:922: In CMOVL32rr: X86cmov node requires exactly 4 operands!
def CMOVL32rr : I<0x4C, MRMSrcReg,       // if <s, GR32 = GR32
^

instead of just:

CMOVL32rr: 	(set GR32:i32:$dst, (X86cmov GR32:$src1, GR32:$src2))
/Users/sabre/llvm/Debug/bin/tblgen: In CMOVL32rr: X86cmov node requires exactly 4 operands!

This is all I plan to do with this, but it should be easy enough to improve if anyone 
cares (e.g. keeping more loc info in "dag" expr records in tblgen.

268cfea6bc Fun x86 encoding tricks: when adding an immediate value of 128, 
use a SUB instruction instead of an ADD, because -128 can be
encoded in an 8-bit signed immediate field, while +128 can't be.
This avoids the need for a 32-bit immediate field in this case.

A similar optimization applies to 64-bit adds with 0x80000000,
with the 32-bit signed immediate field.

To support this, teach tablegen how to handle 64-bit constants.

f53af44e09 lib/Target/SubtargetFeature.cpp asserts that the FeatureKV[] table be sorted 
by its first field, but TableGen doesn't actually enforce creating it that 
way. TableGen sorts the records that will be used to create it by the names 
of the records, not the Name field of those records.

This patch corrects the sort to use the "Name" field of the record as the 
sort key.

c2f7fcfbba Major change to tblgen: instead of resolving values every time a class is 
finished up, only resolve fully when the def is defined.  This allows things
to be changed and all uses to be propagated through.  This implements
TableGen/LazyChange.td and fixes TemplateArgRename.td in the process.

None of the .td files used in LLVM backends are changed at all by this
patch.

8dcbaf2f98 Add initial support for list slices. This currently allows you to do stuff 
like this:

def B {
  list<int> X = [10, 20, 30, 4, 1, 1231, 20] [2-4,2,2,0-6];
}

... which isn't particularly useful, but more is to come.
