Chandler Carruth 14aae04029 Fix some rather confusing indentation and control flow in the errno 
printing routine. This is made harder to see due to the surprising
formatting, inconsistent brace usage, and repeated conditions that all
test the same thing.

The only "consequence" of this bug is re-assigning 'str' to an empty
string when computing the error string for an error number of 0 in the
event of a non-GNU strerror_r routine. So, nothing to see here other
than cleanup. It did help me find PR17055 in clang-format though.

Reid Kleckner 37f69de11b Remove dead or useless header checks from cmake and autoconf 
On Windows, this improves clean cmake configuration time on my
workstation from 1m58s to 1m32s, which is pretty significant.  There's
probably more that can be done here, but this is the low hanging fruit.

Eric volunteered to regenerate ./configure for me.

NAKAMURA Takumi 38f4c93837 llvm/lib/Support/Errno.cpp: [Win32] Fix usage of strerror_s(). 
FYI, two arguments of strerror_s() is provided in C++ on msvc.

NAKAMURA Takumi 189111808e lib/Support/Errno.cpp: Check strerror_s() with HAVE_DECL_STRERROR_S in config.h.*. 
AC_CHECK_FUNCS seeks a symbol only in libs. We should check the declaration in string.h.

FIXME: I have never seen mingw(s) have strerror_s() (not _strerror_s()).
FIXME: Autoconf/CMake may seek strerror_s() with the definition MINGW_HAS_SECURE_API in future.
