AAPCS+VFP), similar to fastcall / stdcall / whatevercall seen on x86.
In particular, all library functions should always be AAPCS regardless of floating point ABI used.

Since this is the primary reason for the introduction of this feature, downgrade implementation status to "Some examples work".

diagnosing it as an error rather than looping infinitely. Also,
explicitly disallow @defs in Objective-C++. Fixes <rdar://problem/9260136>.

This is done by pushing physical register definitions close to their
use, which happens to handle flag definitions if they're not glued to
the branch. This seems to be generally a good thing though, so I
didn't need to add a target hook yet.
The primary motivation is to generate code closer to what people
expect and rule out missed opportunity from enabling macro-op
fusion. As a side benefit, we get several 2-5% gains on x86
benchmarks. There is one regression:
SingleSource/Benchmarks/Shootout/lists slows down be -10%. But this is
an independent scheduler bug that will be tracked separately.
See rdar://problem/9283108.
Incidentally, pre-RA scheduling is only half the solution. Fixing the
later passes is tracked by:
<rdar://problem/8932804> [pre-RA-sched] on x86, attempt to schedule CMP/TEST adjacent with condition jump
Fixes:

I've used it a few times to reduce unit tests and gotten one request for information on it. It's not easy to use correctly because bugpoint doesn't tell you when you're doing it wrong.

instruction around, reducing work.
Greatly simplify handling of debug instructions. There is no need to
build up a vector of them and then move them into the one predecessor
if we're processing a block. Instead just rescan the block and *copy*
them into the pred. If a block gets merged into multiple preds, this
will retain more debug info.

It seems we also had an ill-formed test case, mon dieu! Fixes rdar://8576107.

Modified the OptionGroupOptions to be able to specify only some of the options
that should be appended by using the usage_mask in the group defintions and
also provided a way to remap them to a new usage mask after the copy. This
allows options to be re-used and also targetted for specific option groups.
Modfied the CommandArgumentType to have a new eArgTypePlatform enumeration.
Taught the option parser to be able to automatically use the appropriate
auto completion for a given options if nothing is explicitly specified
in the option definition. So you don't have to specify it in the option
definition tables.
Renamed the default host platform name to "host", and the default platform
hostname to be "localhost".
Modified the "file" and "platform select" commands to make sure all options
and args are good prior to creating a new platform. Also defer the computation
of the architecture in the file command until all options are parsed and the
platform has either not been specified or reset to a new value to avoid
computing the arch more than once.
Switch the PluginManager code over to using llvm::StringRef for string
comparisons and got rid of all the AccessorXXX functions in lieu of the newer
mutex + collection singleton accessors.
