match.  Jakob, please take a look when you get a chance.

Chris Lattner 607795f917 comment out a bunch of parallel store patterns that apparently
can't match or just have no testcases.  Will remove after 
confirmation from dan that they really are dead.

Daniel Dunbar 0f7fbb3d00 MC/Mach-O: Add isScatteredFixupFullyResolved, which implements the correct algorithm (used on x86_64) for determining whether an evaluated fixup is fully resolved (doesn't need relocation).
- Test cases will follow, once we have x86_64 relocation support.

Daniel Dunbar 6e13bb07fb MC/Mach-O/x86_64: Add getAtom[ForAddress].

Daniel Dunbar c558ec211f MC/Mach-O: Factor out isSymbolLinkerVisible method; "linker visible" is a made up term to refer to non-temporary labels + temporary labels in sections-which-require symbols. For Darwin, it corresponds to symbols which effectively define an atom.

Chris Lattner 1802b17b65 Finally change the instruction looking map to be a densemap from
record* -> instrinfo instead of std::string -> instrinfo.

This speeds up tblgen on cellcpu from 7.28 -> 5.98s with a debug
build (20%).

Jeffrey Yasskin 71bd0f4eda Bugpoint's default memory limit (100MB) was too low for valgrind, so
this patch raises the default to 800MB when valgrind's active.  800
was chosen semi-arbitrarily.

Chris Lattner 83facb0812 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.

John McCall a332b953e8 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.

Douglas Gregor c6b5a3df1e For debug information, get the main file name from the source manager
rather than from the -main-file-name flag, since the source manager
has proper path information. Fixes <rdar://problem/7769538>.

Chris Lattner fdc20711e8 infer results of a pattern from implicit defs. This allows you to do something
like this:

 def : Pat<(add ...),
           (FOOINST)>;

When fooinst only has a single implicit def (e.g. to R1).  This will be handled
as if written as (set R1, (FOOINST ...))

Jeffrey Yasskin 3eb346caeb Work around a valgrind oddity where it doesn't pass the full path of a
script to the #! command by using bash instead of /bin/sh.  Bash
searches $PATH for its script argument, but dash, which /bin/sh
resolves to on some systems, does not.
https://bugs.kde.org/show_bug.cgi?id=231257 tracks the valgrind
problem.
