libsframe provides an API to find the FRE associated with a given PC in
the program. This patch adds a direct test of this API.
In this test, we create two dummy SFrame FDEs with 4 FREs each. Then we
test that sframe_find_fre () works for the first, second, third and the
last FRE from one of the FDEs. Such a test ensures better regression
testing for the sframe_find_fre () function which is going to be the
bread and butter of an SFrame based stack tracer.
