[TestMiBreak] Print a formatted string via printf in the test case.
Summary:
If the string is not formatted, these can happen when compiled with GCC:
1. If it is a null string "", then GCC completely removes the call to
printf even with -O0.
2. If the string is a single character string, say "\n" for example,
then GCC replaces the call to printf with a call to putchar.
3. If the string length is greater than 1, but is not formatted, then
GCC replaces the call to printf with a call to puts.
All the above will fail the test as we want a breakpoint on "printf" to
hit.
Test Plan: dotest.py -C gcc -p TestMiBreak
