What I sometimes do is copy specific test files to /dev/shm then
compile them with an installed trunk build, using different compiler
options and maybe modifying the file if needed. I use -I. So #include
<testsuite_hooks.h> finds /dev/shm/testsuite_hooks.h which contains:

#include <assert.h>
#define VERIFY assert

Then I can run the executables under gdb or valgrind.

It's quite manual, but if I know I'm trying to test a specific change
I only need to test one or two files that way, not the entire
testsuite.
