Currently, `print_module_map` is only respected for ubsan if it is ran in tandem with asan. This patch adds support for this flag in standalone mode. I copied the pattern used to implement this for asan.
Also added a common `print_module_map` lit test for Darwin only. Since the print messages are different per platform, we need to write a regex test to cover them. This test is coming in a separate patch

Summary:
While working on rdar://problem/62083617 I noticed this call was
missing.
This is a no-op for all platforms except Darwin. For Darwin this
means the `use_xnu_fast_mmap` flag is initialized as it was intended
when using UBSan in standalone mode.

Summary:
This fixes symbolization in Standalone UBSan mode for the Darwin simulators.
861b69faee (rdar://problem/58789439) tried to fix
symbolization for all sanitizers on Darwin simulators but unfortunately it only
fixed the problem for TSan.
For UBSan in standalone mode the fix wasn't sufficient because UBSan's
standalone init doesn't call `Symbolizer::LateInitialize()` like ASan
and TSan do. This meant that `AtosSymbolizerProcess::LateInitialize()`
was never being called before
`AtosSymbolizerProcess::StartSymbolizerSubprocess()` which breaks an
invariant we expect to hold.
The missing call to `Symbolizer::LateInitialize()` during UBSan's
standalone init seems like an accidently omission so this patch simply
adds it.

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 references to renamed files found by that.
