It is possible to be in a situation where more than one funclet token is

Summary:
If a module was unavailable (either a missing requirement on the module
being imported, or a missing file anywhere in the top-level module (and
not dominated by an unsatisfied `requires`)), we would silently treat
inclusions as textual. This would cause all manner of crazy and
confusing errors (and would also silently "work" sometimes, making the
problem difficult to track down).

I'm really not a fan of the `M->isAvailable(getLangOpts(), getTargetInfo(),
Requirement, MissingHeader)` function; it seems to do too many things at
once, but for now I've done things in a sort of awkward way.

The changes to test/Modules/Inputs/declare-use/module.map
were necessitated because the thing that was meant to be tested there
(introduced in r197805) was predicated on silently falling back to textual
inclusion, which we no longer do.

The changes to test/Modules/Inputs/macro-reexport/module.modulemap
are just an overlooked missing header that seems to have been missing since
this code was committed (r213922), which is now caught.

[ScalarEvolutionExpander] Reuse findExistingExpansion during expansion cost calculation for division

Primary purpose of this change is to reuse existing code inside findExistingExpansion. However it introduces very slight semantic change - findExistingExpansion now looks into exiting blocks instead of a loop latches. Originally heuristic was based on the fact that we want to look at the loop exit conditions. And since all exiting latches will be listed in the ExitingBlocks, heuristic stays roughly the same.

Summary:
Increase the estimated costs for insert/extract element operations on
AArch64. This is motivated by results from benchmarking interleaved
accesses.

Add missing costs for zext/sext/trunc instructions and some integer to
floating point conversions. These costs were previously calculated
by scalarizing these operation and were affected by the cost increase of
the insert/extract element operations.

This commit adds a virtual `peekTokens()` function to `MCAsmLexer`
which can peek forward an arbitrary number of tokens.

It also makes the `peekTok()` method call `peekTokens()` method, but
only requesting one token.

The idea is to better support targets which more more ambiguous
assembly syntaxes.

Summary:
When demoting an SSA value that has a use on a phi and one of the phi's
predecessors terminates with catchret, the edge needs to be split and the
load inserted in the new block, else we'll still have a cross-funclet SSA
value.

Add a test for this, and for the similar case where a def to be spilled is
on and invoke and a critical edge, which was already implemented but
missing a test.

  The new field in the MemoryAccess allows us to track a value related
  to that access:
    - For real memory accesses the value is the loaded result or the
      stored value.
    - For straigt line scalar accesses it is the access instruction
      itself.
    - For PHI operand accesses it is the operand value.

  We use this value to simplify code which deduced information about the value
  later in the Polly pipeline and was known to be error prone.
