When 'go tool dist test' stops, it was intended that it first wait for
pending background tests, like a failed compilation waits for pending
background compiles. But these three lines prevented that.
Fix by deleting them. (The actual loop already contains the correct
logic to avoid running the others and to wait for what's left.)

An internal link may need the C compiler support library, libgcc.a. Add
a -libgcc option to set the name of the compiler support library. If
-libgcc is not used, run the compiler to find it. Permit -libgcc=none
to skip using libgcc at all and hope for the best.
Change cmd/dist to not copy libgcc into the distribution. Add tests to
ensure that all the standard packages that use cgo can be linked in
internal mode without using libgcc. This ensures that somebody with a
Go installation without a C compiler can build programs.

The memory sanitizer (msan) is a nice compiler feature that can
dynamically check for memory errors in C code. It's not useful for Go
code, since Go is memory safe. But it is useful to be able to use the
memory sanitizer on C code that is linked into a Go program via cgo.
Without this change it does not work, as msan considers memory passed
from Go to C as uninitialized.
To make this work, change the runtime to call the C mmap function when
using cgo. When using msan the mmap call will be intercepted and marked
as returning initialized memory.
Work around what appears to be an msan bug by calling malloc before we
call mmap.

hacky fast paths for avoiding the 1 second "go list" latency are now
removed and only apply to the case where partial tests are run via
args, instead of regex. The build coordinator will use both styles
