[r15-6415 Regression] FAIL: gfortran.dg/coarray_lib_comm_1.f90 -Os scan-tree-dump-times original "_gfortran_caf_get_by_ct \\(caf_token.., 0B, 0B, 1, \\(unsigned long\\) atmp.[0-9]+.span" 4 on Linux/x86_64

[Andre Vehreschild]

Hi all,

I did an ooppsie with the patch for 107635. Attached is a patch that fixes
this. Essentially the regexp was to complicated for what was needed. So now we
just count the number of occurrences of caf_get_by_ct, which has to be four.

Regtests ok on x86_64-pc-linux-gnu. Ok for mainline?

Regards,
	Andre
