Copied all the map test cases for the compiler module to the hipe testsuite.
Included generated test suites in the HiPE test Emakefile.

This makes them be included when running the tests for the hipe
module.
Made the failing testcases skip, so that failures implies regressions

Modified lib/hipe/test/hipe_testsuite_driver.erl so that case file
test/0 functions may return {skip, Comment}.
Merge branch 'hipe-maps-tests' into hipe-maps

Add the compiler tests for maps to HiPE, skipping the ones that use
instructions that are not yet supported.
