Add inline implementations of arm bus_space_read/write_N().
Revise the arm bus_space implementation to avoid dereferencing the tag on
every operation to retrieve the bs_cookie value almost nothing actually uses.
Use the explicit member initializer style to init the bus_space struct.
Use arm/bus_space-v6.c for all armv6 systems
Consolidate many identical implementations of bus_space to a single
common tag and implementation shared by armv4 and armv6.
Micro-optimize the new arm inline bus_space implementation by grouping all
the data the inline functions access together at the start of the bus_space
struct so that they all fit in a single cache line.

Synchronize the default C++ stack in stable/10 with head, by merging
almost all recent changes to libc++ and libcxxrt.
MFC r256642:
Since C++ typeinfo objects are currently not guaranteed to be merged at
runtime by the dynamic linker, check for their equality in libcxxrt by
not only comparing the typeinfo's name pointers, but also comparing the
full names, if necessary. (This is similar to what GNU libstdc++ does
in its default configuration.) The 'deep' check can be turned off again
by defining LIBCXXRT_MERGED_TYPEINFO, and recompiling libcxxrt.
