Fix use-of-uninitialized value when RWX memory can't be allocated (PR6701).
SELinux doesn't allow 'execmem', returning MAP_FAILED and 'Permission denied'
for mmap or RWX memory. In this case AllocateRWX was returning a MemoryBlock
with uninitialized fields, which sometimes caused crashes.
This patch initializes MemoryBlock fields to 0, so that the RWX-failure check
works.
It doesn't fix the SELinux 'execmem' issues though (the JIT will not work when
SELinux is in enforcing mode).

If we mark clean-ups as clean-ups, then it could break when inlining through an
'invoke' instruction. You will get a situation like this:
bb:
%ehptr = eh.exception()
%sel = eh.selector(%ehptr, @per, 0);
...
bb2:
invoke _Unwind_Resume_or_Rethrow(%ehptr) %normal unwind to %lpad
lpad:
...
The unwinder will see the %sel call as a clean-up and, if it doesn't have a
catch further up the call stack, it will skip running it. But there *is* another
catch up the stack -- the catch for the %lpad. However, we can't see that. This
is fixed in code-gen, where we detect this situation, and convert the "clean-up"
selector call into a "catch-all" selector call. This gives us the correct
semantics.
