[AVR32] Fix compile error with gcc 4.1

gcc 4.1 doesn't seem to like const variables as inline assembly
outputs. Drop support for reading 64-bit values using get_user() so
that we can use an unsigned long to hold the result regardless of the
actual size. This should be safe since many architectures, including
i386, doesn't support reading 64-bit values with get_user().

[AVR32] Optimize the TLB miss handler

Reorder some instructions and change the register usage to reduce
the number of pipeline stalls. Also use the bfextu and bfins
instructions for bitfield manipulations instead of shifting and
masking.

This makes gzipping a 80MB file approximately 2% faster.
