The existing /*FALLTHROUGH*/ comments work with GCC but not Clang, so this commit adds a FALLTHROUGH macro that uses the 'fallthrough' attribute if the compiler supports it. Refer to https://bugs.chromium.org/p/chromium/issues/detail?id=995993 NOTE: All versions of GCC that support -Wimplicit-fallthrough also support the 'fallthrough' attribute, but certain other compilers (Oracle Solaris Studio, for instance) support /*FALLTHROUGH*/ but not the 'fallthrough' attribute. Thus, this commit retains the /*FALLTHROUGH*/ comments, which have existed in the libjpeg code base in some form since 1994 (libjpeg v5.) Closes #531
