configure: Add a test for the minimum compiler version
So far we only had implicit requirements for the minimum compiler version,
e.g. we require at least GCC 4.1 for the support of atomics. However,
such old compiler versions are not tested anymore by the developers, so
they are not really supported anymore. Since we recently declared explicitly
what platforms we intend to support, we can also get more explicit on the
compiler version now. The supported distributions use the following version
of GCC:
RHEL-7: 4.8.5
Debian (Stretch): 6.3.0
Debian (Jessie): 4.8.4
OpenBSD (ports): 4.9.4
FreeBSD (ports): 8.2.0
OpenSUSE Leap 15: 7.3.1
Ubuntu (Xenial): 5.3.1
macOS (Homebrew): 8.2.0
So we can safely assume GCC 4.8 these days. For Clang, the situation is
a little bit more ambiguous, since it is sometimes not available in the
main distros but rather third party repositories. At least Debian Jessie
uses version 3.5, and EPEL7 for RHEL7 uses 3.4, so let's use 3.4 as
minimum Clang version now - we still can adjust this later if necessary.
Unfortunately Apple uses different version numbers for the Clang that is
included in their Xcode suite, so we need to check the version numbers
for Xcode separately. Xcode 5.1 seems to be the first one that has been
shipped with LLVM 3.4, so use this version as the minimum there.

configure: Remove obsolete check for Clang < 3.2
Since we have got a check for Clang >= 3.4 now, we do not need to
check for older Clang versions in the configure test for 128-bit ints
anymore.

Now that we require at least GCC 4.8, we don't need this als workaround
for 4.6 and 4.7 anymore.

tcg/tcg.h: Remove GCC check for tcg_debug_assert() macro
Both GCC v4.8 and Clang v3.4 (our minimum versions) support
__builtin_unreachable(), so we can remove the version check here now.

Since we require GCC version 4.8 or newer now, we can be sure that
the builtin functions are always available on GCC. And for Clang,
we can check the availablility with __has_builtin instead.

Clang 3.4 considers duplicate typedef in ppc4xx_i2c.h and
bitbang_i2c.h an error even if they are identical. Move it to a common
place to allow building with this clang version.
