Restore "Function bitcode index in Value Symbol Table and lazy reading support"

This reverts commit r247898 (which reverted r247894).

Patch fixed to address two issues exposed by buildbots:
- unused variable warning in NDEBUG mode
- std::initializer_list lifetime issue causing test failures

Original Summary:
Support for including the function bitcode indices in the Value Symbol
Table. This requires writing the VST after the function blocks, which in
turn requires a new VST forward declaration record encoding the offset of
the full VST (which is backpatched to contain the offset after the VST
is written).

This patch also enables the lazy function reader to use the new function
indices out of the VST. This support will be used by ThinLTO as well, which
will be in a follow on patch. Backwards compatibility with older bitcode
files is maintained.

A new test is also included.

The bitcode format (used for the lazy reader as well as the upcoming
ThinLTO patches) came out of discussions with Duncan and others and is

so I enabled them at r243687. However, Escha soon notified us of a bug not covered by any in-tree regression tests:
if we don't propagate the flags, we may fail to CSE DAG nodes because differing FMF causes them to not match. There is
one test case in this patch to prove that point.

This patch hopes to fix or leave a 'TODO' for all of the in-tree places where we create nodes that are FMF-capable. I
did this by putting an assert in SelectionDAG.getNode() to find any FMF-capable node that was being created without FMF
( D11807 ). I then ran all regression tests and test-suite and confirmed that everything passes.

This patch exposes remaining work to get DAG FMF to be fully functional: (1) add the flags to non-binary nodes such as
FCMP, FMA and FNEG; (2) add the flags to intrinsics; (3) use the flags as conditions for transforms rather than the
current global settings.

7 years ago[IndVars] Fix PR24783.
Sanjoy Das [Tue, 15 Sep 2015 23:45:39 +0000 (23:45 +0000)]
[IndVars] Fix PR24783.

In `IndVarSimplify::ExpandSCEVIfNeeded`,
`SCEVExpander::findExistingExpansion` may return an `llvm::Value` that
differs in type from the SCEV it was asked to find an expansion for (but
computes the same value).  In such cases, we fall back on
`expandCodeFor`; and rely on LLVM to CSE the two equivalent
expressions (different only by a no-op cast) into a single computation.

I tried a few other approaches to fixing PR24783, all of which turned
out to be more complex than this current version:

 1. Move the `ExpandSCEVIfNeeded` logic into `expandCodeFor`.  This got
    problematic because currently we do not pass in the `Loop *` into
    `expandCodeFor`.  Changing the interface to do this is a more
    invasive change, and really does not make much semantic sense unless
    the SCEV being passed in is an add recurrence.

    There is also the problem of `expandCodeFor` being used in places
    other than `indvars` -- there may be performance / correctness
    issues elsewhere if `expandCodeFor` is moved from always generating
    IR from scratch to cache-like model.

 2. Have `findExistingExpansion` only return expression with the correct
    type.  This would make `isHighCostExpansionHelper` and thus
    `isHighCostExpansion` more conservative than necessary.

 3. Insert casts on the value returned by `findExistingExpansion` if
    needed using `InsertNoopCastOfTo`.  This is complicated because
    `InsertNoopCastOfTo` depends on internal state of its
    `SCEVExpander` (specifically `Builder.GetInserPoint()`), and this
    may not be set up when `ExpandSCEVIfNeeded` is called.

 4. Manually insert casts on the value returned by
    `findExistingExpansion` if needed using `InsertNoopCastOfTo` via
    `CastInst::Create`.  This is probably workable, but figuring out the
    location where the cast instruction needs to be inserted has enough

LTO: Disable extra verify runs in release builds

The verifier currently runs three times in LTO: (1) after parsing, (2)
at the beginning of the optimization pipeline, and (3) at the end of it.

The first run is important, since we're not sure where the bitcode comes
from and it's nice to validate it, but in release builds the extra runs
aren't appropriate.

This commit:
  - Allows these runs to be disabled in LTOCodeGenerator.
  - Adds command-line options to llvm-lto.
  - Adds command-line options to libLTO.dylib, and disables the verifier
    by default in release builds (based on NDEBUG).

This shaves about 3.5% off the runtime of ld64 when linking
