separate aggregate temporary and then memcpy it over to the
destination. This fixes a regression I introduced with r133235, where
the compound literal on the RHS of an assignment makes use of the
structure on the LHS of the assignment.

I'm deeply suspicious of AggExprEmitter::VisitBinAssign()'s
optimization where it emits the RHS of an aggregate assignment
directly into the LHS lvalue without checking whether there is any
aliasing between the LHS/RHS. However, I'm not in a position to
revisit this now.

Big thanks to Eli for finding the regression!

* We should change the generated code because of a debug use.
* Avoid creating debug uses of undef, as they become a kill.

* rounding modes for fp add, mul, sub now use .rn
* float -> int rounding correctly uses .rzi not .rni
* 32bit fdiv for sm13 uses div.rn (instead of div.approx)
* 32bit fdiv for sm10 now uses div (instead of div.approx)

Approx is not IEEE 754 compatible (and should be optionally set by a flag to the backend instead). The .rn rounding modifier is the PTX default anyway, but it's better to be explicit.

All these modifiers should be available by using __fmul_rz functions for example, but support will need to be added for this in the backend.

config.cache will be used by the person who specifies '-C' to configure.
config.cache's inconsistency should be responsible to him.

Re-configuration would spend so much on cygming without '-C', esp. cygwin.

they should still be officially __strong for the purposes of errors, 
block capture, etc.  Make a new bit on variables, isARCPseudoStrong(),
and set this for 'self' and these enumeration-loop variables.  Change
the code that was looking for the old patterns to look for this bit,
and change IR generation to find this bit and treat the resulting         
variable as __unsafe_unretained for the purposes of init/destroy in
the two places it can come up.

Thanks to John for the prodding.

C++, which means:
  - binding the temporary as needed in Sema, so that we generate the
  appropriate call to the destructor, and
  - emitting the compound literal into the appropriate location for
  the aggregate, rather than trying to emit it as a temporary and
  memcpy() it.

Fixes PR10138 / <rdar://problem/9615901>.

The reserved R14-R15 are always saved in the prolog, and using CSRs
starting from R13 allows them to be saved in one instruction.

Thanks to Anton for explaining this.

function:

platform select --sysroot /Volumes/remote-root remote-macosx

Each platform subclass is free to interpret the sysroot as needed.

Modified the communication and connection classes to not require the
BytesAvailable function. Now the "Read(...)" function has a timeout in
microseconds.

Fixed a lot of assertions that were firing off in certain cases and replaced
them with error output and code that can deal with the assertion case.

  Add a test case for the SBTarget::AttachToProcessWithID() API call.

o main.c:

  The change goes with the added test case test_with_dwarf_and_attach_to_process_with_id_api() above.

o SBTarget.cpp:

  Checks whether we're in synchronous mode.  If yes, let's wait for the process to stop right after attaching.
