fix handling of 64-bit arguments to Method.invoke on 32-bit architectures
...
The previous code failed to account for alignment padding in the
Double and Long classes.

fix putstatic/putfield for 64-bit volatiles
...
We must call acquireMonitorForObject before popping the
putstatic/pushfield operands off the stack to avoid clobbering said
operands.

fix a couple of 64-bit-op-on-32-bit-system bugs
...
We weren't properly handling the case where a 64-bit value is
multipled with itself in multiplyRR, leading to wrong code. Also,
addCarryCR didn't know how to handle constants more than 8-bits wide.

disable Math.abs(long) intrinsic on 32-bit x86
...
It never worked and caused the compiler to crash instead due to an
impossible-to-fulfill constraint.

fix 64-bit left shifts with constant shifts greater than or equal to 32
...
The shiftLeftC function in powerpc.cpp was miscompiling such shifts,
leading to crashes due to illegal instructions and other weirdness due
to instructions that meant something completely different. This
commit fixes that and adds a test to Longs.java to make sure it stays
fixed.
