Sys: add PetscFunctionBeginHot to switch to cheaper pointer checks

Some logging and debugging operations are expensive. In particular,
applications can see order of magnitude slowdowns when PetscCheckPointer
configures a special signal handler (debug builds only). Additionally,
high-frequency events like MAT_SetValues are disabled by default because
it can be expensive to profile.

My marking "hot" regions, we can turn off the expensive operations by
default, but still have the ability to enable them at run-time. This
commit adds PetscFunctionBeginHot, with logic in PetscCheckPointer to
skip the check while inside a "hot" function.

PetscStack: use same definitions for PetscStack functions

If the user compiles their code with debugging, perhaps calling
PetscStack functions, it would be useful for the implementations to make
a best-effort at displaying the stack usefully when they subsequently
LD_PRELOAD an optimized version of the library. These functions are
tiny so code size is not an excuse for keeping the complexity of
different versions.
