fb31ccb68c A slight reworking of the custom patterns for x86-64 tpoff codegen and 
correct the testcase for valid assembly.

Needs more tests.

62e4c671b6 MC/X86: Subdivide immediates a bit more, so that we properly recognize immediates based on the width of the target instruction. For example: 
addw $0xFFFF, %ax

8b1190a540 Rather than having a ton of patterns for double shift instructions, e.g. SHLD16rrCL, just perform custom dag combine to form x86 specific dag so they match to the same pattern. This also makes sure later dag combine do not cause isel to miss them (e.g. promoting i16 to i32).

e3486a4c9a Now that tblgen can handle matching implicit defs of instructions 
to input patterns, we can fix X86ISD::CMP and X86ISD::BT as taking
two inputs (which have to be the same type) and *returning an i32*.
This is how the SDNodes get made in the graph, but we weren't able
to model it this way due to deficiencies in the pattern language.

Now we can change things like this:

 def UCOM_FpIr80: FpI_<(outs), (ins RFP80:$lhs, RFP80:$rhs), CompareFP,
-                  [(X86cmp RFP80:$lhs, RFP80:$rhs),
-                   (implicit EFLAGS)]>; // CC = ST(0) cmp ST(i)
+                  [(set EFLAGS, (X86cmp RFP80:$lhs, RFP80:$rhs))]>;

and fix terrible crimes like this:

-def : Pat<(parallel (X86cmp GR8:$src1, 0), (implicit EFLAGS)),
+def : Pat<(X86cmp GR8:$src1, 0),
           (TEST8rr GR8:$src1, GR8:$src1)>;

This relies on matching the result of TEST8rr (which is EFLAGS, which is
an implicit def) to the result of X86cmp, an i32.

1840991d54 factor the 'sign extended from 8 bit' patterns better so 
that they are not destination type specific.  This allows
tblgen to factor them and the type check is redundant with
what the isel does anyway.
