fix the second part of rdar://8366474 - clang fails to parse ObjC selectors with '::', when :: isn't the first part of the selector.

It couldn't be used outside of the file because SDISelAsmOperandInfo
is local to SelectionDAGBuilder.cpp. Making it a static function avoids
a weird linkage dance.

platform implies default visibility. To achieve these, refactor our
lookup of explicit visibility so that we search for both an explicit
VisibilityAttr and an appropriate AvailabilityAttr, favoring the
VisibilityAttr if it is present.

Reformatted doc comments so that they are now difficult to edit in any editor that doesn't have explicit doxygen support, as per LLVM style guidelines.

There are two ways that a later store can comletely overlap a previous store:

1. They both start at the same offset, but the earlier store's size is <= the
   later's size, or
2. The earlier store's offset is > the later's offset, but it's offset + size
   doesn't extend past the later's offset + size.

the attribute appertains is unavailable on that platform.

Correctly terminate the range of register DBG_VALUEs when the register is
clobbered or when the basic block ends.

The code is now ready to deal with variables that are sometimes in a register
and sometimes on the stack. We just need to teach emitDebugLoc to say 'stack
slot'.

the following '@'.  Conceivably, we could skip tokens until something that
can validly start an @interface declaration here, but it's not clear that
it matters.

masks to match inversely for the code as is to work. For the example given
we actually want:

bfi r0, r2, #1, #1

not #0, however, given the way the pattern is written it's not possible
at the moment.

This is a work in progress as the interface for producing symbolic operands is
not done.  But a hacked prototype using information from the object file's
relocation entiries and replacing immediate operands with MCExpr's has been
shown to work with no changes to the instrucion printer.  These APIs will be
moved into a dynamic library at some point.
