22b7685401 Reland "[hwasan] Add definitions for missing operator delete functions" 
Looks like builders were failing for the sized variants of operator
delete. These are hidden behind the __cpp_sized_deallocation macro
which can be defined with -fsized-deallocation.

_GLIBCXX_RELEASE wasn't defined before GCC 7.1.

c990d56d42 [HWASan] Use hwasan_memalign for aligned new. 
Aligned new does not require size to be a multiple of alignment, so
memalign is the correct choice instead of aligned_alloc.

Fixes false reports for unaligned sizes.

This reverts commit 4fb7c120fed504519d167c93ed9d920aeae46fb0.
Breaks tests on Linux were system gcc doesn't support C++17
(but gcc used to build LLVM does), see https://reviews.llvm.org/D119161
