    Background: since gccgo does not currently merge identical types at link time,
    the reflect function canonicalize() exists to choose a canonical specimen
    for each set of identical types.
    In this way, user code has the guarantee that identical types
    will always compare as ==
    
    Change: arrange reflect functions MapOf(), SliceOf(), StructOf() etc.
    to call canonicalize() on the types they create, before storing the types
    in internal lookup caches and returning them.
    
    This fixes known cases where canonicalize() is needed but was missing.
    Supersedes https://golang.org/cl/112575 and mostly fixes issue 25284.

When trying to compile something with arm_acle.h using G++ we get a number of nasty errors:
arm_acle.h:48:49: error: invalid conversion from ‘const void*’ to ‘const int*’ [-fpermissive]
    return __builtin_arm_ldc (__coproc, __CRd, __p);

This is because the intrinsics that are supposed to be void return the "result" of their builtin,
which is void. C lets that slide but C++ complains.

After fixing that we run into further errors:
arm_acle.h:48:46: error: invalid conversion from 'const void*' to 'const int*' [-fpermissive]
    return __builtin_arm_ldc (__coproc, __CRd, __p);
                                               ^~~
Because the pointer arguments in these intrinsics are void pointers but the builtin
expects int pointers. So this patch introduces new qualifiers for void pointers and their
const-qualified versions and uses that in the specification of these intrinsics.

This gives us the opportunity of creating an arm subdirectory in g++.dg and inaugurates it
with the first arm-specific C++ tests (in that directory).
