Owen Anderson 660466ed42 I just fail with SVN today.

Owen Anderson 1e8ae64f83 Convert the internal PassRegistrar class into a new, external PassRegistry class. No intended functionality change at this point.

Owen Anderson 81781220d2 Speculatively revert r108813, in an attempt to get the self-host buildbots working again. I don't see why this patch 
would cause them to fail the way they are, but none of the other intervening patches seem likely either.

Daniel Dunbar 4a35d6f8cd Revert r108794, "Separate PassInfo into two classes: a constructor-free 
superclass (StaticPassInfo) and a constructor-ful subclass (PassInfo).", it is
breaking teh everything.

Owen Anderson e7c5fe586a Separate PassInfo into two classes: a constructor-free superclass (StaticPassInfo) and a constructor-ful subclass (PassInfo).

Owen Anderson 0edf6a1131 Change the implemented interfaces list on PassInfo from a std::vector to a manually implemented 
linked list.  This is a little slower and involves more malloc'ing, but these lists are
typically short, and it allows PassInfo to be entirely constant initializable.

Chris Lattner 718da70ca2 Fix PR7658, a problem where type refinement can trigger 
constant replacement which was botching its handling of
types.  Use of getType() instead of getRawType() was causing
the type map in constant folding to be updated wrong.

Gabor Greif 03e7e68caa rotate CallInst operands 
with this commit the callee moves to the end of
the operand array (from the start) and the call
arguments now start at index 0 (formerly 1)

this ordering is now consistent with InvokeInst

this commit only flips the switch,
functionally it is equivalent to
r101465

I intend to commit several cleanups after a few
days of soak period

Nick Lewycky 5d373c2141 If it's safe to speculatively execute load(alloca) the it's safe to execute 
load(gep(alloca)) where the gep is all-zeros. There's more we could do here but
this is a common case.

Chris Lattner 9380b81837 use PrintEscapedString to handle attribute section with escapes in it, 
PR7399.  The asm parser already handles this.  This is of dubious 
utility (see the PR) but the asmprinter was clearly broken here.

Bill Wendling 03bcd6ecc8 Implement the "linker_private_weak" linkage type. This will be used for 
Objective-C metadata types which should be marked as "weak", but which the
linker will remove upon final linkage. However, this linkage isn't specific to
Objective-C.

For example, the "objc_msgSend_fixup_alloc" symbol is defined like this:

      .globl l_objc_msgSend_fixup_alloc
      .weak_definition l_objc_msgSend_fixup_alloc
      .section __DATA, __objc_msgrefs, coalesced
      .align 3
l_objc_msgSend_fixup_alloc:
       .quad   _objc_msgSend_fixup
       .quad   L_OBJC_METH_VAR_NAME_1

This is different from the "linker_private" linkage type, because it can't have
the metadata defined with ".weak_definition".

Currently only supported on Darwin platforms.

Gabor Greif eec74583ca encode operand initializations (at fixed index) 
in terms of Op<> and ArgOffset. This works for
values of {0, 1} for ArgOffset.
Please note that ArgOffset will become 0 soon and
will go away eventually.
