Run C tests on all platforms (#270)

* Run C tests on all platforms

* Don't install llvm on mac & add windows define

* Update blst settings for windows

* Install msvc on windows

* Don't specify blst as a library

* Try including -lmingw32

* Clean up makefile & test setting target

* Try using gcc for windows

* Don't treat warnings as errors on windows

* Test upping stack size

* Ignore some tasks on windows

* Clean up some things

* Fix indentations

* Delete extra blank line

* More organization

* Remove windows check around sanitize

* Move XCRUN initialization back to top

* Move extra sanitize cflags out like the others
