ac19a35444 Move tree navigation to a new Path class that doesn't have to be a template. 
The path also holds a reference to the root node, and that allows important
iterator accessors like start() and stop() to have no conditional code. (When
the compiler is clever enough to remove it.)

6f39fefae0 Remove explicit uses of -emit-llvm, the test infrastructure adds it 
automatically.  Use -S with llvm-gcc rather than -c, so tests can
work when llvm-gcc is really dragonegg (which can output IR with -S
but not -c).  Yes, dragonegg supports objective-c++ (poorly though).

31fddf4883 Judging from the comment, the system assembler is supposed to assemble 
the output of this test.  Since it was producing bitcode, that clearly
wasn't happening!  Have it produce target assembler and assemble that
instead.

9b721e8233 Using LLVMCC_EMITIR_FLAG rather than hard-coding -emit-llvm 
(dragonegg cannot use -emit-llvm so needs a different flag
to everyone else).

7bda5159fa It seems inconsistent to have LLVMCC_EMITIR_FLAG and 
LLVMGCC_DISABLEOPT_FLAGS, one with CC in it, the other
with GCC.  Rename LLVMGCC_DISABLEOPT_FLAGS to
LLVMCC_DISABLEOPT_FLAGS.

0e324a205e 1. Fixing error where basic block labels were not being printed out when they need to be for the MBlaze backend because AsmPrinter::isBlockOnlyReachableByFallthrough does not take into account delay slots. 
2. Re-adding .mask and .frame directives in printed assembly.
3. Adding .ent and .end directives in printed assembly.
4. Minor cleanups to MBlaze backend.

1cf4810406 Generalize overflowLeaf to also handle overflows in branch nodes.

8d7096e8ca The srem -> urem transform is not safe for any divisor that's not a power of two. 
E.g. -5 % 5 is 0 with srem and 1 with urem.
