Summary: For platforms which support slow unwinder only, we restrict the store context size to 1, basically only storing the current pc. We do this because the slow unwinder which is based on libunwind is not async signal safe and causes random freezes in forking applications as well as in signal handlers.

Summary: This is an initial setup in order to move some additional tests from Linux onto Posix.
I also moved decorate_proc_maps onto the Linux directory
Finally added msan's definition for "stable-runtime".
Only a test requires it, and its commit message (r248014) seems to imply
that AArch64 is problematic with MSan.

Summary:
Previously, the tests only ran for the 64-bit equivalent of the default target
(see -m64).
Given the supported architecture list only contains 64-bit targets, this happens
to work out the same as the supported targets in most cases but may matter for
X86_64/X86_64h on Darwin.
For other targets, the practical effect is that the test names contain the
architecture. This resolves some confusion when msan tests fail since their
name no longer implies that they are trying to test the default target.

We are interested in verifying that -gline-tables-only provides enough
debug information for verbose error reports and symbolized stack traces.
