Sanjoy Das de47590589 [IndVars] Fix PR25576
`LCSSASafePhiForRAUW` as computed was incorrect -- in cases like
these (this exact example does not actually trigger the bug):

define i32 @f(i32 %n, i1* %c) {
entry:
  br label %outer.loop

outer.loop:
  br label %inner.loop

inner.loop:
  %iv = phi i32 [ 0, %outer.loop ], [ %iv.inc, %inner.loop ]
  %iv.inc = add nuw nsw i32 %iv, 1
  %tc = udiv i32 %n, 13
  %be.cond = icmp ult i32 %iv, %tc
  br i1 %be.cond, label %inner.loop, label %inner.exit

inner.exit:
  %iv.lcssa = phi i32 [ %iv, %inner.loop ]
  %outer.be.cond = load volatile i1, i1* %c
  br i1 %outer.be.cond, label %outer.loop, label %leave

leave:
  %iv.lcssa.lcssa = phi i32 [ %iv.lcssa, %inner.exit ]
  ret i32 %iv.lcssa.lcssa
}

`LCSSASafePhiForRAUW` is true for `%iv.lcssa` when re-rewriting the exit
value of `%iv` for `%inner.loop` to `%tc` (this can happen due to
`SCEVExpander::findExistingExpansion`), but the RAUW breaks LCSSA.

To fix this, instead of computing `SafePhi` with special logic, decide
the safety of RAUW directly via `replacementPreservesLCSSAForm`.

David Majnemer 413111952a [MS ABI] Don't crash while mangling recursive lambdas
We might get into bad situations where we try to embed the signature of
an inner lambda into an outer lambda which cannot work: the inner lambda
wants to embed the name of the outer lambda!

Instead, omit the return type for lambdas.

This fixes PR26105.

N.B.  While we are here, make lambdas nested within functions use an
artificial scope so that they can get demangled.

Manman Ren 53a54c41d7 CXX_FAST_TLS calling convention: fix issue on x86-64.
%RBP can't be handled explicitly. We generate the following code:
    pushq %rbp
    movq  %rsp, %rbp
    ...
    movq  %rbx, (%rbp)  ## 8-byte Spill
where %rbp will be overwritten by the spilled value.

The fix is to let PEI handle %RBP.

Justin Lebar 55c83325ae Respect bound archs, even when they don't alter the toolchain.
Summary:
It's possible to BindArch without changing the toolchain at all.  For
example, armv7 and armv7s have exactly the same toolchain triple.

Therefore the code in the Driver that checks that we're not creating a
job for the same Action twice needs to consider (Action, Toolchain,
BoundArch) tuples.

Alexey Samsonov 95cd990588 [LSan] Ignore all allocations made inside pthread_create.
Thread stack/TLS may be stored by libpthread for future reuse after
thread destruction, and the linked list it's stored in doesn't
even hold valid pointers to the objects, the latter are calculated
by obscure pointer arithmetic.

With this change applied, LSan test suite passes with
"use_ld_allocations" flag defaulted to "false". It still requires more
