 LLVM 3.2 is out as of mid December. We need to update the backend to
 support it.

 There seems to be a number of new bugs due to the change.

 With LLVM 3.1 we get the following testsuite failures:

 {{{

 OVERALL SUMMARY for test run started at Mon Jan 14 21:42:32 PST 2013
     3552 total tests, which gave rise to
    13164 test cases, of which
        0 caused framework failures
    11606 were skipped

     1515 expected passes
       23 had missing libraries
       15 expected failures
        0 unexpected passes
        5 unexpected failures

 Unexpected failures:
 *  codeGen/should_run        cgrun044 [exit code non-0] (optllvm)
 *  concurrent/should_run     367_letnoescape [bad exit code] (optllvm)
 *  numeric/should_run        arith005 [bad stdout] (optllvm)
    typecheck/should_compile  tc226 [exit code non-0] (optllvm)
    typecheck/should_compile  tc235 [exit code non-0] (optllvm)
 }}}

 Where the failures marked with '*' are unique to the LLVM backend.

 With LLVM 3.2 we get the following:

 Where failures marked with '*' are unique to the LLVM backend and failures
 marked with '**' are unique to LLVM 3.2 relative to 3.1.

 I believe bootstrapping with LLVM also fails now. However, that may be due
 to the change to the new-code-generator, and not of LLVM 3.1 -> 3.2. I'll
 create a separate ticket for that.
