[965] Fix TTM relocation caching overzealousness.
The failure mode that was a available was:
reloc 1 -> target_buf
exec: PRESUMED_OFFSET wrong, buffer migrates, r1 entry updated.
reloc 2 -> target_buf
exec: suppose buffer migrates again. PRESUMED_OFFSET wrong. r2 entry updated.
reloc 1 -> target_buf
exec: suppose buffer doesn't migrate. PRESUMED_OFFSET right. no relocations
performed. r1 has stale pointer at original location.
Failures were reported with OGLconform's VBO test and SPECviewperf90, though
I haven't confirmed that this fixes it.
