ext/bigdecimal/bigdecimal.c: Backport #2349 [ruby-core:26646]; fix comparisons. Also fix a bunch of bugs that lead to broken-ness and failing tests.
test/bigdecimal/test_bigdecimal.rb: Backport #2349 [ruby-core:26646]; added a test suite. test/ruby/test_exception.rb: The test suite was breaking ZeroDivisionError, which in turn would break bigdecimal/test_bigdecimal.rb. Made a simple fix that keeps that test but does so non-destructively. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/branches/ruby_1_8_6@29025 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
