Add a DirExists mechanism, modeled after FileExists. Use it to guard
creation of the report path directory.
This should avoid failures running the sanitizer in a sandbox where the
file creation attempt causes hard failures, even for an existing
directory. Problem reported on D109794 for ChromeOS in sandbox
(https://issuetracker.google.com/209296420).

When setting the report path, recursively create the directory as
needed. This brings the profile path support for memprof on par with
normal PGO. The code was largely cloned from __llvm_profile_recursive_mkdir
in compiler-rt/lib/profile/InstrProfilingUtil.c.

llvm-libc is expected to be built with sanitizers and not use interceptors in
the long run. For now though, we have a hybrid process, where functions
implemented in llvm-libc are instrumented, and glibc fills and sanitizer
interceptors fill in the rest.
Current sanitizers have an invariant that the REAL(...) function called from
inside of an interceptor is uninstrumented. A lot of interceptors call strlen()
in order to figure out the size of the region to check/poison. Switch these
callsites over to the internal, unsanitized implementation.

lib/CMakeFiles/SanitizerLintCheck.dir/build.make:57: recipe for target 'lib/CMakeFiles/SanitizerLintCheck' failed
I do not know why this apparently wasn't a problem when the files
had extension .cc.

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 $(basename $f) . ; done
and manually updated references to renamed files found by that.
