S/390: Fix vector all/any cc modes.
This fixes a problem with the vector compares producing CC mode
results.
The instructions produce condition code modes which can be either
interpreted to check an ALL elements or an ANY element result. As the
modes where used before they could not be inverted by the middle-end
by inverting the comparison code (e.g. eq to ne). The result usually
was just wrong.
In fact inverting a comparison code on an CCVALL mode would require to
also change the mode to CCVANY but this cannot be done easily in the
middle-end. With this patch the meaning of an ALL cc mode only refers
to the not-inverted comparison code (e.g. eq, gt, ge). With that
change inverting the comparison code matches a not operation on the
condition code mask again.
Bootstrapped and regression tested on s390 and s390x.

compiler: add slice initializers to the GC root list
As of https://golang.org/cl/32917 we can put slice initializers in the
.data section. The program can still change the values in those
slices. That means that if the slice elements can contain pointers,
we need to register the entire initializer as a GC root.
This would be straightforward except that we only have a Bexpression
for the slice initializer, not an Expression. So introduce a
Backend_expression type that wraps a Bexpression as an Expression.

runtime: print C functions in traceback
Since gccgo can trace back through C code as easily as Go code, we
should print C functions in the traceback.
This worked before https://golang.org/cl/31230 for a dumb reason. The
default value for runtime.traceback_cache was, and is, 2 << 2, meaning
to print all functions. The old C code for runtime_parsedebugvars
would return immediately and do nothing if the environment variable
GODEBUG was not set (if GODEBUG was set it would later call
setTraceback. The new Go code for runtime.parsedebugvars does not
return immediately if GODEBUG is not set, and always calls
setTraceback. Either way, if GOTRACEBACK is not set, setTraceback
would set traceback_cache to 1 << 2, meaning to only print non-runtime
functions and having the effect of not printing plain C functions.
Keep the current handling of GODEBUG/GOTRACEBACK, which matches the gc
library, but add an extra check to print C functions by default.

2016-11-30 Andre Vehreschild <vehre@gcc.gnu.org>
* caf/libcaf.h: Add new action types for (de-)registration of
allocatable components in derived type coarrays. Add _caf_is_present
prototype.
* caf/single.c (_gfortran_caf_register): Add support for registration
only and allocation of already registered allocatable components in
derived type coarrays.
(_gfortran_caf_deregister): Add mode to deallocate but not deregister
an allocatable component in a derived type coarray.
(_gfortran_caf_is_present): New function. Query whether an
allocatable component in a derived type coarray on a remote image is
allocated.

* check.c (gfc_check_allocated): By pass the caf_get call and check on
the array.
* gfortran.h: Add optional flag to gfc_caf_attr.
* gfortran.texi: Document new enum values and _caf_is_present function.
* primary.c (caf_variable_attr): Add optional flag to indicate that the
expression is reffing a component.
(gfc_caf_attr): Likewise.
* trans-array.c (gfc_array_deallocate): Handle deallocation mode for
coarray deregistration.
(gfc_trans_dealloc_allocated): Likewise.
(duplicate_allocatable): Use constants instead of
creating custom constant tree node of zero or one. Use gfc_add_modify
convenience function.
(duplicate_allocatable_coarray): This function is similar to
duplicate_allocatable but tailored to handle coarrays.
(caf_enabled): Check whether in-derived-type coarray processing is
enabled.
(caf_in_coarray): Check that in-derived-type coarray processing is
enabled and currently in a derived-typed coarray.
(gfc_caf_is_dealloc_only): Return true, when deallocate only is
desired for components in derived typed coarrays.
(structure_alloc_comps): A mode for handling coarrays, that is no
longer encode in the purpose. This makes the use cases of the
routine more flexible without repeating. Allocatable components in
derived type coarrays are now registered only when nullifying an
object and allocated before copying data into them.
(gfc_nullify_alloc_comp): Use the caf_mode of structure_alloc_comps
now.
(gfc_deallocate_alloc_comp): Likewise.
(gfc_deallocate_alloc_comp_no_caf): Likewise.

(gfc_alloc_allocatable_for_assignment): Make use to the cheaper way of
reallocating a coarray without deregistering and reregistering it.
(gfc_trans_deferred_array): Initialize the coarray token correctly for
deferred variables and tear them down on exit.
* trans-array.h: Change some prototypes to add the coarray (de-)
registration modes. Add prototype for checking if deallocate only is
selected for components in derived typed coarrays.
* trans-decl.c (gfc_build_builtin_function_decls): Generate the
declarations for the changed/new caf-lib routines.
(gfc_trans_deferred_vars): Ensure deferred variables are (de-)
registered correctly on procedure entry/exit.
(generate_coarray_sym_init): Use constants.
* trans-expr.c (gfc_conv_procedure_call): Propagate coarray allocation
modes accordingly.
(gfc_trans_alloc_subarray_assign): Likewise.
(gfc_trans_subcomponent_assign): Likewise.
(gfc_trans_structure_assign): Generate code to register the components
of a derived type coarray prior to initialization.
(gfc_conv_structure): Set flag that the structure is in a coarray.
(gfc_trans_scalar_assign): Add flag to indicate being in a coarray and
set the structure_alloc_comps modes correctly.
(gfc_trans_assignment_1): Figure being in a coarray expression.
* trans-intrinsic.c (gfc_conv_intrinsic_caf_get): Adapt to new
structure_alloc_comps interface.
(conv_caf_send): Use the old API as long as possible.
(trans_caf_is_present): Generate code to check whether an allocatable
component in a derived typed coarray is allocated on a remote image.
(caf_this_image_ref): Return true, when only reffing this image.
(gfc_conv_allocated): Convert allocated queries on allocatable
components to the library API.

structure_alloc_comps.

deallocating allocatable components in derived type coarras.
* trans.c (gfc_allocate_using_lib): Renamed to
gfc_allcate_using_caf_lib.
(gfc_allocate_allocatable): Set the registration mode/type of caf-
register calls adapting to all the possible allocatable objects.
(gfc_deallocate_with_status): Add deregistration mode for allocatable
components in derived type coarrays.
(gfc_deallocate_scalar_with_status): Likewise.
* trans.h (enum gfc_coarray_type): Renamed to gfc_coarray_regtype to
