[SyntaxTree] Extend the syntax tree dump to also cover `NodeRole`

We should see `NodeRole` information in the dump because that exposes how the
accessors will behave.

Functional changes in the dump:
* Surround Leaf tokens with `'`
* Append `Node` dumps with `NodeRole` information, except for unknown roles
* Append marks to `Node` dumps, instead of prepending

Non-functional changes:
* `::dumpTokens(llvm::raw_ostream, ArrayRef<syntax::Token>, const
SourceManager &SM)` always received as parameter a `syntax::Token *`
pointing to `Leaf::token()`. Changed the function to
`dumpLeaf(llvm::raw_ostream, syntax::Leaf *, const SourceManager&)`
* `dumpTree` acted on a Node, rename to `dumpNode`

[compiler-rt][asan][test] Set LD_LIBRARY_PATH_{32,64} on Solaris

The dynamically linked ASan tests rely on `LD_LIBRARY_PATH` to find
`libclang_rt.asan-*.so` at runtime.

However, the Solaris runtime linker `` also supports more specific
variables: `LD_LIBRARY_PATH_32` and `LD_LIBRARY_PATH_64` respectively.  If
those happen to be set, `LD_LIBRARY_PATH` is ignored.  In such a case, all
dynamically linked ASan tests `FAIL`.  For i386 alone, this affects about
200 tests.

The following patch fixes that by also setting `LD_LIBRARY_PATH_{32,64}` on

Tested on `amd64-pc-solaris2.11` both with only `LD_LIBRARY_PATH` set and
with `LD_LIBRARY_PATH_{32,64}` set too.

[InstCombine] PHI-of-insertvalues -> insertvalue-of-PHI's

As per statistic, this happens pretty exceedingly rare,
but i have seen it in exactly the situations the
Phi-aware aggregate reconstruction would have handled,
eventually, and allowed invoke -> call fold later on.

So while this might be something that other fold
will have to learn about, i believe we should be
doing this transform in general.

Here, we are okay with adding two PHI's to get both the base aggregate,
and the inserted value. I'm not sure it makes much sense to restrict
it to a single phi (to just the inserted value?), because originally
we'd be receiving the final aggregate already..

Commit e19ef1aab524ef10a2d118adcd9f6fd6ca2d7ca9 by flo
[DSE,MemorySSA] Cache accesses with/without reachable read-clobbers.

Currently we repeatedly check the same uses for read clobbers in some
cases. We can avoid unnecessary checks by keeping track of the memory
accesses we already found read clobbers for. To do so, we just add
memory access causing read-clobbers to a set. Note that marking all
visited accesses as read-clobbers would be to pessimistic, as that might
include accesses not on any path to  the actual read clobber.

If we do not find any read-clobbers, we can add all visited instructions
to another set and use that to skip the same accesses in the next call.

[SVE] Fix TypeSize related warnings with IR truncates of scalable vectors

In getCastInstrCost when the instruction is a truncate we were relying
upon the implicit TypeSize -> uint64_t cast when asking if a given type
has the same size as a legal integer. I've changed the code to only
ask the question if the type is fixed length.

I have also changed InstCombinerImpl::SimplifyDemandedUseBits to bail
out for now if the type is a scalable vector.

I've added the following new tests:


for both of these fixes.
