4a2b684ef4 modify SAVE_XMM for potential 64bit use 
the win64 abi requires saving and restoring xmm6:xmm15. currently
SAVE_XMM and RESTORE XMM only allow for saving xmm6:xmm7. allow
specifying the highest register used and if the stack is unaligned.

When the license headers were updated, they accidentally contained
trailing whitespace, so unfortunately we have to touch all the files
again.

63ea8705eb some XMM registers are non-volatile on windows x64 ABI 
XMM6 to XMM15 are non-volatile on Windows x64 ABI.  We have to save
these registers.
