eviously, using `memory history` command on an executable
which wasn't compiled with ASAN would yield following error:
(lldb) mem hist 0x0
error: no available memory history provider
Looking at the help message for this command didn't really
make this error message any clearer.
This patch changes the `help memory history` description to
at least mention how a history provider could be set up.
After the patch:
(lldb) help mem hist
Print recorded stack traces for allocation/deallocation events associated
with an address.
This command requires a memory history provider plugin to be present. For
example, compile the debuggee with address sanitizer.
