Nick Terrell 6d25a633ea lib: Prepare zstd for preboot environment, improve performance ... These changes are necessary to get the build to work in the preboot environment, and to get reasonable performance: - Remove a double definition of the CHECK_F macro when the zstd library is amalgamated. - Switch ZSTD_copy8() to __builtin_memcpy(), because in the preboot environment on x86 gcc can't inline `memcpy()` otherwise. - Limit the gcc hack in ZSTD_wildcopy() to the broken gcc version. See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81388. ZSTD_copy8() and ZSTD_wildcopy() are in the core of the zstd hot loop. So outlining these calls to memcpy(), and having an extra branch are very detrimental to performance.
