Modified gcc/clang warning suppression macros to account for some warnings flags being supported by one compiler but not the other (#379)
* Committing clang-format changes
* Fixed GCC warning suppression pragmas to also work with clang
H5_GCC_DIAG_ON remains gcc-only.
Added a new H5_CLANG_DIAG_ON that's clang-only, but it's not used anywhere currently.
Added a new H5_GCC_CLANG_DIAG_ON that works with both compilers, which afterall support mostly the same warnings. Changed almost all uses of H5_GCC_DIAG_ON to use H5_GCC_CLANG_DIAG_ON, with the exception of a couple, where they really were suppressing gcc-only warnings.
* Committing clang-format changes
