Alexander Korotkov 993bdb9f93 pg_attribute_no_sanitize_alignment() macro 
Modern gcc and clang compilers offer alignment sanitizers, which help to detect
pointer misalignment.  However, our codebase already contains x86-specific
crc32 computation code, which uses unalignment access.  Thankfully, those
compilers also support the attribute, which disables alignment sanitizers at
the function level.  This commit adds pg_attribute_no_sanitize_alignment(),
which wraps this attribute, and applies it to pg_comp_crc32c_sse42() function.
