Introduce `art::FastExit` to replace all uses of `quick_exit` in ART.
No longer use `quick_exit(3)` in ART, as it does not play well with
Clang's code coverage instrumentation (see b/187935521 and
b/186576313). Replace all its uses with a new routine,
`art::FastExit`, calling either `exit(3)` when ART is built with
Clang's code coverage instrumentation (in order to dump coverage
profiles when the program terminates) or `_exit(2)` otherwise (to exit
quickly).
Function `art::FastExit` is implemented as part of the
`art_libartbase_headers` header library, so that it can be used easily
in `dalvikvm`.
