symbol names.

createTempSymbol would still add a suffix to make sure a new symbol was always
returned, but it kept a single counter. Because of that, if we were to use
just createTempSymbol("cu_begin"), the label could change from cu_begin42 to
cu_begin43 because some other code started using temporary labels.

specialized counters.

asan: optimization experiments

The experiments can be used to evaluate potential optimizations that remove

some instrumentation, you set Exp to a non-zero value (mask of optimization
experiments that want to remove instrumentation of this instruction).
If Exp is non-zero, this pass will emit special calls into runtime
(e.g. __asan_report_exp_load1 instead of __asan_report_load1). These calls
make runtime terminate the program in a special way (with a different
exit status). Then you run the new compiler on a buggy corpus, collect
the special terminations (ideally, you don't see them at all -- no false
negatives) and make the decision on the optimization.

The exact reaction to experiments in runtime is not implemented in this patch.

Fix R0 use in PowerPC VSX store for FastIsel.

The VSX stores are sometimes generated with a undefined index register, causing %noreg to be used and R0 to be emitted later on. The semantics of the VSX store (e.g. stdsdx) requires R0 to be used as base if we want zero to be used in the computation of the effective address instead of the content of R0. This patch checks if no index register was generated and forces R0 to be used as base address.

Verifier: Don't call debug info verifier if the module is broken

If `Verifier` has already found a failure, don't call
`DebugInfoVerifier`.  The latter sometimes crashes in `DebugInfoFinder`
when the former would give a nice message.  The only two cases I found
it crashing are explicit verifier tests I've added:

  - test/Verifier/llvm.dbg.declare-expression.ll
  - test/Verifier/llvm.dbg.value-expression.ll

However, I assume frontends with bugs will create invalid IR as well.

IMO, the `DebugInfoVerifier` should never crash (instead, it should fail
to verify), but subtleties like that will be easier to work out once
it's enabled again.

  - Empty `filename:` fields in `MDFile`s.  Compile units and some types
    require non-empty filenames.  A number of testcases have empty
    filenames, probably due to hand-reduction of testcases.
  - Not-quite empty arrays: `!{i32 0}`.  This used to be equivalent in
    the debug info schema to `!{}`.  They cause problems for
    `!MDSubroutineType`'s `types:` array, since it requires all operands
    to be valid types.  (Note that `!{null}` is the correct type array
    for functions that take no arguments and return `void`.)
  - Significantly bitrotted testcases.  Nodes got left behind a few
    upgrades ago because of missing or invalid tags.
