Add weak definitions for the load/store callbacks.

This matches the weak definitions for all other SanitizerCoverage
callbacks.

Xiaodong Liu 56b5f00186 [sancov][sanitizer-common] Correct sanitizer coverage point
Sanitizer coverage point should be the previous instruction PC of the
caller and the offset to the previous instruction might be different
on each CPU architecture.

Dmitry Vyukov 595d340dce sanitizer_common: make internal/external headers compatible
This is a follow up to 4f3f4d6722
("sanitizer_common: fix __sanitizer_get_module_and_offset_for_pc signature mismatch")
which fixes a similar problem for msan build.

I am getting the following error compiling a unit test for code that
uses sanitizer_common headers and googletest transitively includes
sanitizer interface headers:

In file included from third_party/gwp_sanitizers/singlestep_test.cpp:3:

Dmitry Vyukov 4f3f4d6722 sanitizer_common: fix __sanitizer_get_module_and_offset_for_pc signature mismatch
This fixes the following error:

sanitizer_interface_internal.h:77:7: error: conflicting types for
     '__sanitizer_get_module_and_offset_for_pc'
  int __sanitizer_get_module_and_offset_for_pc(
common_interface_defs.h:349:5: note: previous declaration is here
int __sanitizer_get_module_and_offset_for_pc(void *pc, char *module_path,

I am getting it on a code that uses sanitizer_common (includes internal headers),
but also transitively gets includes of the public headers in tests
via an internal version of gtest.

Kostya Serebryany 11c533e1ea [sanitizer coverage] write the pc-table at the process exit
The current code writes the pc-table at the process startup,
which may happen before the common_flags() are initialized.
Move writing to the process end.
This is consistent with how we write the counters and avoids the problem with the uninitalized flags.
Add prints if verbosity>=1.
