The first patch is a refactoring moving the clobber generation in gfc_conv_procedure_call where it feels more appropriate. The second patch is a fix for the ICE originally motivating my work on this topic. The third patch is a fix for some wrong code issue discovered with an earlier version of this series. The following patches are gradual condition loosenings to enable clobber generation in more and more cases. Each patch has been tested through an incremental bootstrap and a partial testsuite run on fortran *intent* tests, and the whole lot has been run through the full fortran regression testsuite. OK for master?
