fix float to integer conversion
...
Java requires that NaNs be converted to zero and that numbers at or
beyond the limits of integer representation be clamped to the largest
or smallest value that can be represented, respectively.

fix incorrect array sizing in populateMultiArray
...
We were assuming the array element size was always the native word
size, which is not correct in general for primitive arrays, and this
led to wasted space at best and memory corruption at worst.

Fixed tests for floatToIntBits. Probably want to add more comprehensive tests tomorrow (or today... as of 2 minutes)

Initial attempt at resolving SWT3.7 missing operatons in Avian. Everything seems to be working except floatToIntBits, hence the test case failing.

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 reversed arguments to maybeRex in sseMoveRR
...
This was causing 8-byte SSE-to-SSE moves involving registers
xmm8-xmm15 to be misencoded on x86_64, leading to incorrect code
generation in methods with lots of local variables of type double.

refactor code responsible for moving data in the compiler
...
This is partially to address incorrect code generation for 64-bit
floating-point values on x86_32 and partially to reduce unnecessary
moves.
