Some apps and libraries may generate recoverable SEH exceptions on
Windows, in which cases we don't want to waste time and disk space
generating memory dumps.

We now properly forward the errno value from the child when execvp()
fails, which the parent then uses to for the errno message as well as
including the failed command's name in the message.
In the tails=true build, the calling method cannot always be
determined due to stack frames being optimized away, so we must be
prepared for LogRecord.getSourceMethodName to return null.
We must throw an AbstractMethodError when such a call is executed (not
when the call is compiled), so we compile this case as a call to a
thunk which throws such an error.
Singletons may have embedded object references, and if they are
allocated at fixed memory locations (e.g. if they are larger than
64KB), they must have object masks so the garbage collector knows were
to find said references.
We can't reduce a conditional branch to an unconditional jump unless
both arguments to the comparison are constants *and* those constants
have been resolved. The latter may not be true in the case of a
bootimage build.
We had be using System::Monitor::wait to block threads internally in
the VM as well as to implement Object.wait. However, the interrupted
flag should only be cleared in the latter case, not the former. This
commit adds a new method and changes the semantics of the old one in
order to acheive the desired behavior.
Recent versions of Cygwin's GCC no longer support the -mno-cygwin flag
(compilation works, but linking fails). However, Cygwin now includes
mingw64-i686-gcc, mingw64-x86_64-gcc, and related packages, so we use
those compilers instead. This has the added benefit that we can build
native x86_64 binaries on Cygwin now.
This will break the build for old Cygwin installs, so it will be
necessary to upgrade Cygwin and install the aforementioned packages to
build Avian going forward.
