[PULL 14/21] tests/tcg: remove old SSE tests

[Paolo Bonzini]

The new testsuite is much more comprehensive, so remove the old one;
it is also buggy (the pinsrw test uses incorrect constraints, with =
instead of +, and the golden output for the fxsave tests differs depending
on how the C library uses SSE and AVX instructions).
