curl-compilers.m4: fix compiler_num for clang
...
"clang -dumpversion" always returns "4.2.1", the GCC version that clang
was initially compatible to. Use "clang -v" instead, which returns the
actual clang version.
Fixes https://github.com/curl/curl/issues/1522

curl-compilers.m4: accept -Og and -Ofast GCC flags
...
-Og, introduced in GCC 4.8, optimizes for debugging experience.
-Ofast, introduced in GCC 4.7, builds on -O3 and enables further
optimizations breaking strict standards compliance.
When specified in CFLAGS, these were always overridden by -O0 or -O2.
Fix this by adding them to flags_opt_all.

curl-compilers.m4: turn implicit function declarations into errors
...
This adds -Werror-implicit-function-declaration for GCC 2.95+ so that
these errors are visible at the point where they occur instead of only
at link time.
Implicit function declarations are illegal in C99 and C++ anyway, and
the same warning has been turned into an error for ICC in commit
3072c5b8a1
.

curl-compilers.m4: improve detection of GCC's -fvisibility= flag
...
Some builds of GCC produce output on both stdout and stderr when --help
--verbose is used. The 2>&1 redirection caused them to be arbitrarily
interleaved with each other because of stream buffering. Consequently,
grep failed to match the fvisibility= string in the mixed output, even
though the string was present in GCC's standard output.
This led to silently disabling symbol hiding in some builds of curl.

When nothing is told to configure, we should not enforce switching off
debug options with -g0 (or similar). We instead don't use -g at all in
that situaion and therefore allow the user's CFLAGS settings possibly
