SVD(...,DivideConquer=>...) -- whether to use the LAPACK divide and conquer SVD algorithm

Description

For large matrices, this algorithm is often much faster.

i1 : M = random(RR^200, RR^200);

                200         200
o1 : Matrix RR      <-- RR
              53          53

i2 : time SVD(M);
 -- used 0.0618141s (cpu); 0.0248888s (thread); 0s (gc)

i3 : time SVD(M, DivideConquer=>true);
 -- used 0.269851s (cpu); 0.0812031s (thread); 0s (gc)
