tcg: Use softmmu fast path for unaligned accesses

This patch integrates several commits from Qemu ToT in order to improve
tcg infrastructure for better unaligned accesses handling. These tcg updates
bring performance gain for all architectures which support misaligned access
in hardware.

Makefile.qemu2-sources.mk is updated to include the new file tcg/tcg-op.c.
