Summary:
The workaround added in rL301240 for stderr/out/in symbols being both
macros and globals is only necessary for glibc, and it does not compile
with musl libc. Alpine Linux has had the following fix for it:
https://git.alpinelinux.org/cgit/aports/plain/main/llvm4/llvm-fix-DynamicLibrary-to-build-with-musl-libc.patch
Adapt the fix in our DynamicLibrary.inc for Unix.

libraries are properly unloaded when llvm_shutdown is called.
Summary:
This was mostly affecting usage of the JIT, where storing the library handles in
a set made iteration unordered/undefined. This lead to disagreement between the
JIT and native code as to what the address and implementation of particularly on
Windows with stdlib functions:
JIT: putenv_s("TEST", "VALUE") // called msvcrt.dll, putenv_s
JIT: getenv("TEST") -> "VALUE" // called msvcrt.dll, getenv
Native: getenv("TEST") -> NULL // called ucrt.dll, getenv
Also fixed is the issue of DynamicLibrary::getPermanentLibrary(0,0) on Windows
not giving priority to the process' symbols as it did on Unix.

The changes are causing the i686-mingw32 build to fail.
This reverts commit r301153, and the changes for a separate warning on i686-mingw32 in r301155 and r301156.
