rGcdae6d7711d6: [lldb] Fix one leak in reproducer
Summary

Use a variable of static storage duration to reference an intentionally
leaked variable. A static data area is in the GC-set of various leak
checkers.

This fixes 3 check-lldb-shell tests in a -DLLVM_USE_SANITIZER={Leaks,Address} build,
e.g. test/Shell/Reproducer/TestHomeDir.test

@JDevlieghere The Reproducer library seems to have several other leaks. Maybe you'd like to look at them? :) I am unfamiliar with the code...
For example, lldb-shell :: Reproducer/TestMultipleTargets.test has the following issues:

This is no longer a leak (at least in the technical sense of "never freed, but also never inaccessible). Either remove this comment, or figure out if this is a load-bearing leak :)

@JDevlieghere The Reproducer library seems to have several other leaks. Maybe you'd like to look at them? :) I am unfamiliar with the code...

Unfortunately I don't have bandwidth to look at that right now. IIRC there were a few places where we leaked on purpose during replay (we shouldn't be leaking anything during capture tho), but I'd have to take another look at the code to remember the details.

Can this code execute more than once? If it does I guess it'll really leak?

(if it's not meant to be called more than once, maybe something like:

static std::string *x = nullptr;
assert(!x);
x = new std::string(argv0);

The function is only executed once.

If that's not enforced in any way (at least I can't see any) & the rest of the code looks like it would be OK being called more than once (I think?) - might be worth some checking?

The function is oneshot and from the called functions it should be clear the function cannot be executed more than once (otherwise, duplicate error messages).

I changed the function to static so that it is clear this is not used a library function.
