[GH #926] Add a test for sort method of ResizableIntegerArray PMC
[GH #927] Added tests for sort() method of ResizableFloatArray PMC
[GH #926] Extended sort() tests of ResizableIntegerArray PMC

The tests of the sort() method weren't testing that after resizing the
array, that the sort() method still works (the array is resizable after all
:-) ).  This commit adds these extra tests.
[GH# 927] Test output more specific wrt how float array was resized
[GH #927] Test sort() after unshift in ResizableFloatArray

It's probably a good idea to check if sorting after an unshift works as well
as the currently available tests for simply sorting and for sorting after a
push.  This way we test the interaction between resizing and sorting.

[GH #175] sort.pir benchmark reports how many elements were sorted

This gives us output which can be checked in the benchmarks.t test, such
that the sort.pir test can be added to the benchmarks test suite
Moved vim-relevant lines to its own section in main .gitignore
Ignoring vim backup (~) files
Ignoring gcov and gcov2perl automatically generated files

These files turn up when one runs 'make cover' and don't need to be in the
output from 'git status'
Ignoring html files generated by 'cover' in 'make cover'
Remove gcov-generated files in root parrot dir with 'make cover-clean'

The *.gcov, *.gcda, *.gcno files, which are generated by gcov, are also
output in the base parrot directory.  'make cover-clean' didn't remove these
files.  This commit corrects this issue.
Removing cover-generated html files in 'make cover-clean'
Added frontend/pbc_disassemble to list of coverage directories
[GH #175] Add the sort benchmark to the benchmark test suite
[GH #175] sort_ffa.pir benchmark prints number of elements sorted

It's good to see that a program gives some output to the user, so that we
know that *something* happened.  Now we have this output and can add the
relevant search in the benchmarks.t test suite.
[GH #175] Added sort_ffa.pir benchmark to main benchmark suite
[GH #175] Renamed sort.pir benchmark to sort_fia.pir

This makes it more obvious that this benchmark is for sorting
FixedIntegerArrays in much the same way that sort_ffa.pir benchmarks sorting
