I recently added support for <= loops on trunk. ScalarEvolution now

[LLVMdev] Back-edge taken count of loops
hi all,
i am have a project need to compute the back-edge taken count of a loop, and
the "getBackedgeTakenCount" function of ScalarEvolution could do this for
me.
but later i found that ScalarEvolution could not compute loops with test
expression containing a "=", such as:
void scop_func(long A[], long n) {
long i;
for (i = 1; i<= n; i++)
A[i] = 1;
}
after have
