This adapts LV to the new semantics of get.active.lane.mask as discussed in
D86147, which means that the LV now emits intrinsic get.active.lane.mask with
the loop tripcount instead of the backedge-taken count as its second argument.
The motivation for this is described in D86147.

The arm backend does not handle select/select_cc on vectors with scalar
conditions, preferring to expand them in codegenprepare instead. This
usually works except when optimizing for size, where the optsize check
would end up overruling the backend isSelectSupported check.
We could handle the selects in ISel too, but this seems like smaller
code than trying to splat the condition to all lanes.

Currently, when a program header type is unknown, we dont print anything:
```
ProgramHeader {
Type: (0x60000000)
```
With this patch the output will be:
```
ProgramHeader {
Type: Unknown (0x60000000)
```
It was discussed in D85526 and consistent with what we print for
'--sections' already, e.g.:
```
Section {
Name: .sec
Type: Unknown (0x7FFFFFFF)
}

Fixes PR46575.
Bump statistics version to 6.
Without this patch, for a variable described with a location list the stat
'sum_all_variables(#bytes in parent scope covered by DW_AT_location)' is
calculated by summing all bytes covered by the location ranges in the list and
capping the result to the number of bytes in the parent scope. With the patch,
only bytes which overlap with the parent DIE scope address ranges contribute to
the stat. A new stat 'sum_all_variables(#bytes in any scope covered by
DW_AT_location)' has been added which displays the total bytes covered when
ignoring scopes.
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:
Analysis/CostModel/AArch64/sve-trunc.ll
Transforms/InstCombine/AArch64/sve-trunc.ll
for both of these fixes.

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.

Explicitly check that there is a local def prior to the given
instruction in getReachingLocalMIDef instead of just relying on
a nullptr return from getInstFromId.
The dynamically linked ASan tests rely on `LD_LIBRARY_PATH` to find
`libclang_rt.asan-*.so` at runtime.
However, the Solaris runtime linker `ld.so.1` 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
Solaris.
Tested on `amd64-pc-solaris2.11` both with only `LD_LIBRARY_PATH` set and
with `LD_LIBRARY_PATH_{32,64}` set too.

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`

For some reason the ctor homing case was before the template
specialization case, and could have returned false too early.
I moved the code out into a separate function to avoid this.
Also added a run line to the template specialization test. I guess
all the -debug-info-kind=limited tests should still pass with =constructor,
but it's probably unnecessary to test for all of those.
