After all hard work to implement the EHABI and with the test-suite passing, it's time to turn it on by default and allow users to disable it as a work-around while we fix the eventual bugs that show up. This commit also remove the -arm-enable-ehabi-descriptors, since we want the tables to be printed every time the EHABI is turned on for non-Darwin ARM targets. Although MCJIT EHABI is not working yet (needs linking with the right libraries), this commit also fixes some relocations on MCJIT regarding the EH tables/lib calls, and update some tests to avoid using EH tables when none are needed. The EH tests in the test-suite that were previously disabled on ARM now pass with these changes, so a follow-up commit on the test-suite will re-enable them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200388 91177308-0d34-0410-b5e6-96231b3b80d8
