checking of programs done in these two places are combined, which avoids duplicate code and greatly reduces the number of cases in which exec() fails causing Valgrind to bomb out. Also, we can now load some programs we could not previously, such as scripts lacking a "#!" line at the start. Also, the startup failure messages for bad programs match the shell's messages very closely. And I added a whole bunch of regtests to test all this. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@4918
