428: Fix Windows crash on caching compiled artifact. r=syrusakbary a=repi
Memory clone function wasn't able to write to new reserved memory object.
Changed so allocating Memory objects with protection flag allocates commited memory. And added unit test to verify that it doedsn't crash anymore.
Not fully sure this is the best solution though, but fixes this specific clone crash.

414: Exception logging (win32): Handle error codes correctly, add some more strings r=syrusakbary a=hrydgard
Ran into a situation with an unknown exception from Cranelift (will probably report that one separately). Turns out the signum was "1" though which does not seem to correspond to any of the Windows error codes, except possibly STATUS_GUARD_PAGE which is 0x80000001, but only if we lost the top bit somewhere.
On Windows, exceptions seemed to be trapped by callProtected, which is implemented here: cade9a666f/lib/win-exception-handler/exception_handling/exception_handling.c . It did not seem to correctly store and retrieve the exception code, instead always returning 1: ```longjmp(jmpBuf, 1);```
So I fixed it. And now the log output looks like this:
```
unhandled trap at 1560d5e7bab - code #c0000005: segmentation violation
```
