PR c++/70462 - unnecessary base ctor variant with final.
As pointed out in the PR, we don't need base 'tor variants for a final
class, since it can never be a base. I tried also dropping complete
variants for abstract classes, but that runs into ABI compatibility problems
with older releases that refer to those symbols.
* optimize.c (populate_clone_array): Skip base variant if

On AIX, a function has two symbols, a text symbol (with a leading dot)
and a data one (without it).
As the tests must be run only once, only the data symbol can be used to
retrieve the final go symbol. Therefore, all symbols beginning with a dot
are ignored by symtogo.

[Darwin, fixincludes] Fix Darwin9/10 math.h issues.
Darwin has had long long functions for some considerable time and these are
exposed in Darwin8 and Darwin11+ headers. However, for some reason it was
elected to hide them behind __STRICT_ANSI__ and __STDC_VERSION__ on Darwin9
and Darwin10. This is a problem for G++/libstdc++ that expects the functions
to be available for strict ansi (-std=c++14, for example) and without
defining __STDC_VERSION__. The fix here follows the pattern used in
Darwin11+ headers where the functions may be explicitly hidden by defining
__DARWIN_NO_LONG_LONG.
This fixes the tr1 testsuite fails seen on Darwin9 and 10.
