compiler_rt -- separate or part of libc?

[Joerg Sonnenberger <joerg%britannica.bec.de@localhost>]

Hi all,
compiler-rt provides a replacement for almost all of libgcc under
BSD/MIT license. The exception here is the unwinder, but that's a topic
for another day. As there is no longer a license concern, it brings up
the question on whether we want to keep the files in separate library at
all, especially given the cyclic dependencies for some of the edge
cases. There is already some overlap with libc due to the softfloat
layer, so merging the compiler runtime into libc is not without
precendence. Opinions?
