As discussed in the review for D87120 (specifically at
https://reviews.llvm.org/D87120#inline-831939), clean up PrintModuleMap
and DumpProcessMap usage differences. The former is only implemented for
Mac OSX, whereas the latter is implemented for all OSes. The former is
called by asan and tsan, and the latter by hwasan and now memprof, under
the same option. Simply rename the PrintModuleMap implementation for Mac
to DumpProcessMap, remove other empty PrintModuleMap implementations,
and convert asan/tsan to new name. The existing posix DumpProcessMap is
disabled for SANITIZER_MAC.

Running ninja check-sanitizer fails for after that patch (commit
058f5f6fd8) with the following error:
libRTSanitizerCommon.test.nolibc.x86_64.a(sanitizer_posix.cpp.o): In
function `__sanitizer::GetNamedMappingFd(char const*, unsigned long,
int*)':
..../llvm-project/compiler-rt/lib/sanitizer_common/sanitizer_posix.cpp:358:
undefined reference to `fcntl'
clang-12: error: linker command failed with exit code 1 (use -v to see

This patch works around the problem by only calling fcntl if O_CLOEXEC
is not defined.

See https://reviews.llvm.org/D58620 for discussion, and for the commands
I ran. In addition I also ran
for f in $(svn diff | diffstat | grep .cc | cut -f 2 -d ' '); do rg $f . ; done
and manually updated (many) references to renamed files found by that.
