for all non-ppc(32/64) Darwin platforms
o pass the macosx-version-min/iphoneos-version-min to clang as an assembler,
so that it properly sets this information starting with Xcode 7 (solves
errors when targeting the iOS simulator, and warnings about object files
being compiled for a different OS X version when targeting (Mac) OS X)
o the old assembler is still selectable via -Aas-darwin (required with
Xcode 3.1.x and older)
o since the first Xcode version that shipped with Clang is Xcode 3.2, which
is available for Mac OS X 10.6, most users should not encounter any issues
with the new default (in fact, it fixes some tests for x86 because Clang
supports some instructions that "as" doesn't). Clang does not support
Stabs however, so -gs does require the use of -Aas-darwin

GNU as from binutils for Darwin, and Apple's "as" is based on an old
version of GNU as)
o this will not cause any backward compatibility problems, as the
previous identifier for as_darwin was "AS-Darwin" and the compiler
compared the uppercase value of the -A parameter to the identifier,
so it was not explicitly selectable earlier. The new name is "AS",
so it is explicitly selectable via -Aas like on other platforms.

that we can use assembler writers with different conventions from the
currently set target_asm (e.g. an x86 assembler writer for inline assembly
in LLVM IR)

vector subregisters that we cannot represent yet. We only have to
load/store lower single/double precision contents via them though,
so reuse SUBMMS/SUBMMD for now.

TAArch64AppleAssembler to determine whether we have to add extra
parameters to support assembling via a pipe ("as" is a symlink to
clang for Arch64 on OS X, and needs to be explicitly told its going to
receive assembler code from standard input)
git-svn-id: trunk@29952 -
references that directly take the address of a symbol, rather than
of its GOT entry
o use these addressing modes to access local symbols
