More test cases added

While adding a test case for each report_fatal_error() I also added a check for
a frame pointer in function emitPrologue.

One could argue whether test case `ghc-cc-07.ll` checks for a frame pointer or
for a variable length array. I checked and reported for the former since a VLA
requires a frame pointer, however, the pure existence of a frame pointer does
not imply a VLA. Thus checking for a frame pointer---which is not supported in
GHC CC since register r11 is occupied---is more general and catches hopefully
more potential errors.
