[asan] initialize kHighMemEnd at startup (instead of at compile time) to simplify further changes for various address space layouts. Fix asan_allocator2 for PowerPC (tested on 44-bit address space)

A runtime call is used instead.
MSan will stop adding shadow checks on volatile stores soon.

[ASan] Remove the declarations of pthread_workqueue_t and pthread_workitem_handle_t, which are used no more.

We already have Darwin-specific version of this test.

This CL drastically simplifies the way we're hooking the memory allocation routines in ASan on Mac by using dylib interposition to replace the main malloc_zone_* functions. This allows us to avoid replacing the default CFAllocator and drop the CF dependency at all.

Committing this patch will result in the static runtime being broken. A follow-up CL will switch ASan to use the dynamic runtime library.

ASan: disable flexible mapping and offset on Android. It doesn't work for dynamic ASan runtime there

[asan] split asan_test.cc to speedup parallel build (most important if building with a debug clang, which takes a couple of minutes on this large file with templates). More splits to follow

CMake: generalize checking for target availability and add initial support for PowerPC native arch. With this patch, building LLVM on PowerPC native arch produces a working ASan runtime.
