Mark libgte funcs as asm (#1600)

ScaleMatrix

I think these are handwritten because they heavily use $t registers,
which is not like the code gcc produces. It makes sense for these to be
hand-optimized since they are speed-critical. Also, these don't use the
`ctc2` etc. instructions so I don't think it's a mix of C and gte
macros.

I dumped all the remaining gte funcs to a gist if others want to inspect
these https://gist.github.com/sozud/62a6a4a7f751010d435714a5191c46f3
