stage2: change logic for detecting whether the main package is inside
the std package. Previously it relied on realpath() which is not portable.
This uses resolve() which is how imports already work.
* stage2: fix cleanup bug when creating Module
* flatten lib/std/special/* to lib/*
- this was motivated by making main_pkg_is_inside_std false for
compiler_rt & friends.
* rename "mini libc" to "universal libc"

// supported in clang's compiler-rt implementation today in case anyone tries to link an object file

// produced with an old clang version. This requires dynamically loading frameworks, parsing a

// system plist file, and generally adds a fair amount of complexity to the implementation and so
|

// our implementation differs by simply removing that backwards compatability support. We only use

|
// the newer codepath, which merely calls out to the Darwin _availability_version_check API which is
