[SCCP] Don't delete side-effecting instructions

I'm not sure if the `!isa<CallInst>(Inst) &&
!isa<TerminatorInst>(Inst))` bit is correct either, but this fixes the
case we know is broken.

[CloneFunction] Don't remove unrelated nodes from the CGSSC

CGSCC use a WeakVH to track call sites.  RAUW a call within a function
can result in that WeakVH getting confused about whether or not the call
site is still around.

Add R_386_TLS_LE as a relocation having an implicit addend.

TLS on i386 in non-PIE/PIC code seems broken right now, because we don't
properly add the addend encoded in the instruction to the resulting
offset when processing R_386_TLS_LE relocations.

Extend one of the existing tests for TLS on i686 to use an addend.

[msan] Disable prlimit test on glibc < 2.13.
------------------------------------------------------------------------

llvm-svn: 279471

The undefined behaviour (signed integer overflow) is not a regression
in itself as it was already there, but the test exposing it is a
regression compared to rc1, i.e. the lit tests no longer run ubsan-clean.

This commit fixes the test based on Matt's change in r279125 to not
expose the undefined behaviour.

[SLP] Initialize VectorizedValue when gathering

We abort building vectorizable trees in some cases (e.g., if the maximum
recursion depth is reached, if the region size is too large, etc.). If this
happens for a reduction, we can be left with a root entry that needs to be
gathered. For these cases, we need make sure we actually set VectorizedValue to
the resulting vector.

This patch ensures we properly set VectorizedValue, and it also ensures the
insertelement sequence generated for the gathers is inserted at the correct
location.

[Darwin] Stop linking libclang_rt.eprintf.a

Summary:
The eprintf library was added before the general OS X builtins library existed as a place to store one builtin function. Since we have for several years had an actual mandated builtin library for OS X > 10.5, we should just merge eprintf into the main library.

This change will resolve PR28855.

As a follow up I'll also patch compiler-rt to not generate the eprintf library anymore.

optimization even callee has any byval arg.

PR26423: Assert on valid use of using declaration of a function with an undeduced auto return type

For now just disregard the using declaration in this case. Suboptimal,
but wiring up the ability to have declarations of functions that are
separate from their definition (we currently only do that for member
functions) and have differing return types (we don't have any support
for that) is more work than seems reasonable to at least fix this crash.
