compiler: speed up variable initializer sorting
The compiler used to do variable initializer sorting by looping
through all the initialized variables and, for each one, looping
through all the initialized variables and checking for a dependency.
For very large packages with thousands of initialized global
variables, this quadratic loop could take quite a long time.
Change the approach to first loop through all the initialized
variables and fetch all the references to other variables from the
initialization code. Then, loop through them again and this time add
a dependency for each referenced, initialized, variable, while
checking for initialization loops. We still have a nested loop, but
this time the inner loop should normally be short--just the list of
referenced variables, not the list of all variables.

reflect: canonicalize types returned by StructOf() and friends
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.

[arm] PR target/81497: Fix arm_acle.h for C++
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).
