Bugpoint's default memory limit (100MB) was too low for valgrind, so

this patch raises the default to 800MB when valgrind's active. 800

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.

When elevating access along an inheritance path, initialize the computed
...
access to the (elevated) access of the accessed declaration, if applicable,
rather than plunking that access onto the end after we've calculated the
inheritance access.
Also, being a friend of a derived class gives you public access to its
members (subject to later modification by further inheritance); it does
not simply ignore a single location of restricted inheritance.
Also, when computing the best unprivileged path to a subobject, preserve
the information that the worst path might be AS_none (forbidden) rather
than a minimum of AS_private.
