See RFC for background: http://lists.llvm.org/pipermail/llvm-dev/2020-June/142744.html Follow on companion to the clang/llvm instrumentation support in D85948 and committed earlier. This patch adds the compiler-rt runtime support for the memory profiling. Note that much of this support was cloned from asan (and then greatly simplified and renamed). For example the interactions with the sanitizer_common allocators, error handling, interception, etc. The bulk of the memory profiling specific code can be found in the MemInfoBlock, MemInfoBlockCache, and related classes defined and used in memprof_allocator.cpp. For now, the memory profile is dumped to text (stderr by default, but honors the sanitizer_common log_path flag). It is dumped in either a default verbose format, or an optional terse format. This patch also adds a set of tests for the core functionality. Differential Revision: https://reviews.llvm.org/D87120
