memblock tests: add verbose output to memblock tests

Add and use functions and macros for printing verbose testing output.

If the Memblock simulator was compiled with VERBOSE=1:
- prefix_push(): appends the given string to a prefix string that will be
  printed in test_fail() and test_pass*().

- prefix_pop(): removes the last prefix from the prefix string.

- prefix_reset(): clears the prefix string.

- test_fail(): prints a message after a test fails containing the test
  number of the failing test and the prefix.

- test_pass(): prints a message after a test passes containing its test
  number and the prefix.

- test_print(): prints the given formatted output string.

- test_pass_pop(): runs test_pass() followed by prefix_pop().

- PREFIX_PUSH(): runs prefix_push(__func__).

If the Memblock simulator was not compiled with VERBOSE=1, these
functions/macros do nothing.

Add the assert wrapper macros ASSERT_EQ(), ASSERT_NE(), and ASSERT_LT().
If the assert condition fails, these macros call test_fail() before
executing assert().
