The patch is a combination and partial back port of several prs of the mainline (namely, but not the complete list: pr44672, pr65548). The patch needed the counts of builtin_mallocs/frees in allocatable_scalar_13 to be adapted. There are now fewer calls to the memory management routines. Valgrind does not report any memory issues in the modified code, but that does not mean there aren't any. I am happy to hear about any issue, this patch causes (still having issues getting the sanitizer to work). Bootstrapped and regtested on x86_64-linux-gnu/F23. Ok, for gcc-5-branch?
