Fariborz Jahanian c2371eadd6 Fix a corner case of message lookup looking for class methods. 
If all else failed, find the message in class's root's
list of instacne methods!

Bob Wilson 5b15d01ff3 Fix BuildVectorSDNode::isConstantSplat to handle one-element vectors. 
It is an error to call APInt::zext with a size that is equal to the value's
current size, so use zextOrTrunc instead.

Steve Naroff 3f49feeed5 Finish up some fixes related to <rdar://problem/6497631> Message lookup is sometimes different than gcc's. 
- Disallow casting 'super'. GCC allows this, however it doesn't make sense (super isn't an expression and the cast won't alter lookup/dispatch).
- Tighten up lookup when messaging 'self'.

codegen, until such time as codegen is complete enough to turn on with
-fblocks.

Daniel Dunbar 5637208a88 Driver: More Option implementation. 
- Add Options.def file, collects option information.

 - Actual option instantiation is handled lazily by OptTable to allow
   the driver to not need to instantiate all options.

 - cast<> support for Option, other minor tweaks.

Gabor Greif a954a99c40 "Ghostify" embedded sentinels. This is a real win in all cases 
because less bytes are allocated and subobject construction is gone.
For reference how it works, see BasicBlock.h.
Btw. it is very assuring to see that somebody has invented
this ilist-embedded sentinel technique before me :-)

Chris Lattner 8322dc809e make the token lexer allocate its temporary token buffers for

Chris Lattner 9631e1871e Switch attributes to be allocated from the declcontext bump pointer just like 
decls.  This reduces the number of calls to malloc on cocoa.h with pth and
-disable-free from 15958 to 12444 times (down ~3500).

Chris Lattner 1a84994c46 allocate MultiKeywordSelector's out of a bump pointer allocator instead of malloc. 
This has two advantages 1) no more leaking them, 2) fewer calls to malloc.

This changes us from calling malloc 3685/1390/883/2974/1185 times respectively on
16/20/24/28/32 byte objects when parsing cocoa.h with pth and -disable-free to
calling it 2816/1020/702/2903/1168 times each respectively.

Chris Lattner 4192bce91b add a special case for codegen that improves the case where we have 
multiple sequential cases to a) not create tons of fall-through basic blocks
and b) not recurse deeply.  This fixes codegen on 100K deep cases, and improves
codegen on moderate cases from this:

        switch i32 %tmp, label %sw.epilog [
                i32 1000, label %sw.bb
                i32 1001, label %sw.bb1
                i32 1002, label %sw.bb2
                i32 1003, label %sw.bb3
                i32 1004, label %sw.bb4
...
sw.bb:          ; preds = %entry
        br label %sw.bb1

sw.bb1:         ; preds = %entry, %sw.bb
        br label %sw.bb2

sw.bb2:         ; preds = %entry, %sw.bb1
        br label %sw.bb3

sw.bb3:         ; preds = %entry, %sw.bb2
        br label %sw.bb4

to:

        switch i32 %tmp, label %sw.epilog [
                i32 1000, label %sw.bb
                i32 1001, label %sw.bb
                i32 1002, label %sw.bb
                i32 1003, label %sw.bb
                i32 1004, label %sw.bb
sw.bb:  ;; many preds

Chris Lattner 34a2209177 Change Parser::ParseCaseStatement to use an iterative approach to parsing 
multiple sequential case statements instead of doing it with recursion.  This
fixes a problem where we run out of stack space parsing 100K directly nested
cases.

There are a couple other problems that prevent this from being useful in 
practice (right now the example only parses correctly with -disable-free and
doesn't work with -emit-llvm), but this is a start.

I'm not including a testcase because it is large and uninteresting for 
regtesting.

Sebastian, I would appreciate it if you could scrutinize the smart pointer 
gymnastics I do.

Evan Cheng b8905c4e2c Fix PR3701. 1. X86 target renamed eflags register to flags. This matches what llvm-gcc generates so codegen knows flags register is being clobbered by inline asm. 2. BURR scheduler should also check if inline asm nodes can clobber "live" physical registers. Previously it was only checking target nodes with implicit defs.

Dale Johannesen 159d2159ee Temporarily revert 65975, which breaks the llvm-gcc build. 
While the patch is clearly correct in itself, it's become
apparent other places are assuming debug intrinsics are

Bill Wendling 6d2714738f The DAG combiner was performing a BT combine. The BT combine had a value of -1, 
so it changed it into a 31 via the TLO.ShrinkDemandedConstant() call. Then it
would go through the DAG combiner again. This time it had a value of 31, which
was turned into a -1 by TLI.SimplifyDemandedBits(). This would ping pong
forever.

Teach the TLO.ShrinkDemandedConstant() call not to lower a value if the demanded
value is an XOR of all ones.
