This reverts commit ea1826ee57984d4f44fdb4b35a47169d393618ed.
This change is breaking the ability of tests to override the profile
output file. Need to add a mechanism to do that before resubmitting.

[MemProf] Defer profile file setup until dump time
With all of the writing of the memprof profile consolidated into one
place, there is no need to set up the profile file (which creates the
file and also redirects all printing from the runtime to it) until we
are ready to dump the profile.
This allows errors and other messages to be dumped to stderr instead of
the profile file, which by default is in a binary format. Additionally,
reset the output file to stderr after dumping the profile so that any
requested memprof allocator statistics are printed to stderr.

[MemProf] Pass down memory profile name with optional path from clang
Similar to -fprofile-generate=, add -fmemory-profile= which takes a
directory path. This is passed down to LLVM via a new module flag
metadata. LLVM in turn provides this name to the runtime via the new
__memprof_profile_filename variable.
Additionally, always pass a default filename (in $cwd if a directory
name is not specified vi the = form of the option). This is also
consistent with the behavior of the PGO instrumentation. Since the
memory profiles will generally be fairly large, it doesn't make sense to
dump them to stderr. Also, importantly, the memory profiles will
eventually be dumped in a compact binary format, which is another reason
why it does not make sense to send these to stderr by default.
Change the existing memprof tests to specify log_path=stderr when that
was being relied on.
Depends on D89086.

[MemProf] Memory profiling runtime support
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.
