[RuntimeDyldELF] Improve GOT support
Summary:
This is the first in a series of patches to eventually add support for TLS relocations to RuntimeDyld. This patch resolves an issue in the current GOT handling, where GOT entries would be reused between object files, which leads to the same situation that necessitates the GOT in the first place, i.e. that the 32-bit offset can not cover all of the address space. Thus this patch makes the GOT object-file-local.
Unfortunately, this still isn't quite enough, because the MemoryManager does not yet guarantee that sections are allocated sufficiently close to each other, even if they belong to the same object file. To address this concern, this patch also adds a small API abstraction on top of the GOT allocation mechanism that will allow (temporarily, until the MemoryManager is improved) using the stub mechanism instead of allocating a different section. The actual switch from separate section to stub mechanism will be part of a follow-on commit, so that it can be easily reverted independently at the appropriate time.
Test Plan: Includes a test case where the GOT of two object files is artificially forced to be apart by several GB.

This reverts commit r234717, reapplying r234698 (in spirit).
As described in r234717, the original `Verifier` check had a
use-after-free. Instead of storing pointers to "interesting" debug info
intrinsics whose bit piece expressions should be verified once we have
typerefs, do a second traversal. I've added a testcase to catch the
`llc` crasher.
Original commit message:
Verifier: Check for incompatible bit piece expressions
Convert an assertion into a `Verifier` check. Bit piece expressions
must fit inside the variable, and mustn't be the entire variable.
Catching this in the verifier will help us find bugs sooner, and makes

[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.

Add r234615 back, but make sure outs() is binary.
Original message.
Have one raw_fd_ostream constructor forward to the other.
This fixes some odd behaviour differences between the two. In particular,
the version that takes a FD no longer unconditionally sets stdout to binary.

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.

[MC] Write padding into fragments when -mc-relax-all flag is used
Summary:
When instruction bundling is enabled and the -mc-relax-all flag is
set, we can write bundle padding directly into fragments and avoid
creating large number of fragments significantly reducing LLVM MC
memory usage.
