332adac427 [RewriteStatepointsForGC] Move an expensive debugging check to XDEBUG
The check in question is attempting to help find cases where we haven't relocated a pointer at a safepoint we should have.  It does this by coercing the value to null at any safepoint which doesn't relocate it.  

Unfortunately, this turns out to be rather expensive in terms of memory usage and time.  The number of stores inserted can grow with O(number of values x number of statepoints).  On at least one example I looked at, over half of peak memory usage was coming from this check.  

With this change, the check is no longer enabled by default in Asserts builds.  It is enabled for expensive asserts builds and has a command line option to enable it in both Asserts and non-Asserts builds.

79ccb55981 [docs] Update outdated ExtendingLLVM.rst
Summary:
The document is still incomplete in some degrees, but updated to reflect the
latest changes. Anyway we can detail it if any one think it is not enough. For
the sake of it, some useful examples are listed below:

Refer to r113618 "Add X86 MMX type to bitcode and Type" for how to add a new
type.

> One notable change from then is only one thing that ``lib/VMCore`` is renamed
to ``lib/IR``.

Refer to r194760 "Add addrspacecast instruction" for how to add a new
instruction.

the version that takes a FD no longer unconditionally sets stdout to binary.

ea8c159524 Revert "Verifier: Check for incompatible bit piece expressions"
This reverts commit r234698.

This caused a use-after-free: `QueuedBitPieceExpressions` holds onto
references to `DbgInfoIntrinsic`s and references them past where they're
deleted (this is because the verifier is run as a function pass, and
then `verifyTypeRefs()` is called during `doFinalization()`).

I'll include a reduced crasher for `llc` when I recommit the check.

d2069333ee [CodeGen] Split -enable-global-merge into ARM and AArch64 options.
Currently, there's a single flag, checked by the pass itself.
It can't force-enable the pass (and is on by default), because it
might not even have been created, as that's the targets decision.
Instead, have separate explicit flags, so that the decision is
consistently made in the target.

Keep the flag as a last-resort "force-disable GlobalMerge" for now,
for backwards compatibility.

should be replaced with something more robust soon.  In the meantime,
this will let us write the code that produces __C_specific_handler xdata
tables, which we need regardless of how we decide to get finally blocks
through EH preparation.

f5e4c28c3f Generic: Make isMask_N and isShiftedMask_N consistent over 0
Previously, isMask_N returned false for 0 but isShiftedMask_N returned true.
Almost all uses are for pattern matching bitfield operations in the backends,
and expect false (this was discovered because of AArch64's copy of this logic).

Unfortunately, I couldn't put together a small non-fragile test for this. The
nature of the bitfield operations means that this edge case is only really
triggered for nodes like "(and N, 0)", which the DAG combiner is usually very
good at folding away before they get to this stage.
