    Make two slightly mysterious static local variables thread_local
    
    IRC discussion about them:
    
    tml_: erAck: any idea why in ScFormulaCell::GetMatrixEdge those nC and
    nR are static?
    
    tml_: seems to have been since initial import in 2000 (then in a
    different file, and of type USHORT)
    
    tml_: let's assume it is just random insanity
    
    tml_: hmm, no, making them non-static actually breaks a unit test. wow
    
    erAck: tml_: they are reused when the call is for the same matrix
    origin as the last one to not have to recalculate the same thing
    
    tml_: erAck: ah ok
