dbf2bf739f Refactor DynamicLibrary so searching for a symbol will have a defined order and
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 i686-mingw32-RA-on-linux bot is still having errors.

This reverts commit r301236.

ccb223e38e Revert "Refactor DynamicLibrary so searching for a symbol will have a defined order.”
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.
