8a30efc52f only generate crash dumps for access violations and divides-by-zero
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.

8d2ca7aaf5 fix Thread.interrupt deadlock
Previously, we returned immediately from Monitor.wait if we found we
had been interrupted, but this caused deadlock when waiting to enter
the exclusive state, since we never released Machine::stateLock to
allow active threads to transition into the idle state.  This commit
ensures that we at least briefly release the lock without actually
waiting in that case.

7a82ee6b38 add new System::Monitor::waitAndClearInterrupted method
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.

c3fa08c430 fix Thread.interrupt and Thread.interrupted
These were both totally broken; the latter wasn't even implemented.
This commit fixes/implements them and adds a simple test to exercise
them.

ab8e6cdc80 convert classpath paths to absolute paths
This is necessary because some apps expect CodeSource.getLocation() to
return URL containing an absolute path.

SetEvent returns nonzero on success, so the assert was backwards.

2e0770b0f3 fix MSVC build
MSVC doesn't support __attribute__((__packed__)), but both it and GCC
support pack pragmas, so that's what we'll use.

eae79fdb34 clean up MINIDUMP_EXCEPTION_INFORMATION mess in windows.cpp
The last two commits were meant to work around a supposed bug in
mingw-w64's dbghelp.h, but closer inspection reminded me that we're
not using dbghelp.h at all; legacy mingw doesn't have it, so we had to
declare the structures we needed ourselves based on the MSDN
documentation.  What that documentation doesn't mention is that
MINIDUMP_EXCEPTION_INFORMATION is subject to a special, packed layout,
which we must represent using the __packed__ attribute.

8e57639ff5 use packed version of MINIDUMP_EXCEPTION_INFORMATION
dbghelp.dll expects that MINIDUMP_EXCEPTION_INFORMATION has a packed
layout and will crash if it doesn't (at least on 64-bit systems), but
as of this writing mingw-w64's version is not declared to be so.
Hence this workaround.

openjdk build is crashing and there's trouble loading time zone info
from the embedded java.home directory.

f6a52e260b specify CONTEXT::ContextFlags before calling GetThreadContext
Previously, we assumed that the "context" parameter to
GetThreadContext was only an output parameter, but it actually uses at
the value of CONTEXT::ContextFlags on entry to decide what parts of
the structure to fill in.  We were getting lucking most of the time,
because whatever garbage was on the stack at that location had the
necessary bits set.  When we weren't so lucky, we got all zeros for
the register values which sometimes lead to a crash depending on the
state of the thread being examined.

fea92ed995 more work on tail recursion
We now create a unique thunk for each vtable position so as to avoid
relying on using the return address to determine what method is to be
compiled and invoked, since we will not have the correct return address
in the case of a tail call.  This required refactoring how executable
memory is allocated in order to keep AOT compilation working.  Also, we
must always use the same register to hold the class pointer when
compiling virtual calls, and ensure that the pointer stays there until
the call instruction is executed so we know where to find it in the
thunk.
