ee16995e3d Switch lowering: add heuristic for filling leaf nodes in the weight-balanced binary search tree
Sparse switches with profile info are lowered as weight-balanced BSTs. For
example, if the node weights are {1,1,1,1,1,1000}, the right-most node would
end up in a tree by itself, bringing it closer to the top.

However, a leaf in this BST can contain up to 3 cases, and having a single
case in a leaf node as in the example means the tree might become
unnecessarily high.

This patch adds a heauristic to the pivot selection algorithm that moves more
cases into leaf nodes unless that would lower their rank. It still doesn't
yield the optimal tree in every case, but I believe it's conservatibely correct.

40f8babe9a IndVarSimplify: Avoid UB from binding a reference to a null pointer
Calling operator* on a WeakVH whose Value is null hits undefined
behaviour, since we bind the value to a reference. Instead, go through
`operator Value*` so that we work with the pointer itself.

9edccc8b40 InstrProf: When reading, copy the data instead of taking a reference. NFC
This consolidates the logic to read instrprof records into the on disk
hash table's lookup trait and makes us copy the counter data instead
of taking references to it as we read. This will simplify further
changes to the format.

4029c5944b LowerSwitch: Avoid some undefined behaviour
When a case of INT64_MIN was followed by a case that was greater than
zero, we were overflowing a signed integer here. Since we've sorted
the cases here anyway (and thus currentValue must be greater than
nextValue) it's simple enough to avoid this by using addition rather
than subtraction.

9b3369eafc Try to fix generation of LLVMExports.cmake under Visual Studio.
If LLVMDebugInfoPDB links against the DIA SDK then the exports file
would contain an INTERFACE_LINK_LIBRARIES property that contained an
absolute path to ``diaguids.lib`` which used a native windows path (interpreted
as escape sequences when LLVMExports.cmake is imported causing
``find_package(LLVM)`` to fail) rather than the correct CMake style path.

7edd010739 Improve error handling of getRelocationAddend.
This patch changes getRelocationAddend to use ErrorOr and considers it an error
to try to get the addend of a REL section.

If, for example, a x86_64 file has a REL section, that file is corrupted and
we should reject it.

Using ErrorOr is not ideal since we check the section type once per relocation
instead of once per section.

Checking once per section would involve getRelocationAddend just asserting and
callers checking the section before iterating over the relocations.

In any case, this is an improvement and includes a test.

We were in the strange situation that we abstracted over two of them. This makes
section based relocations MachO only.

To disable KASan instrumentation for a certain function attribute((no_sanitize("kernel-address"))) can be used.

What this does is make all symbols that would otherwise start with a .L

Some of these symbols still show up in the symbol table, but we can just
make them unnamed.

In order to make sure we produce identical results when going thought assembly,
all .L (not just the compiler produced ones), are now unnamed.

->
  shuffle(concat(v1, v2), undef)

because we can access quad vectors (see PerformVECTOR_SHUFFLECombine).

This is useful in the general case, but there are special cases where
native shuffles produce larger results: the two-result ops.

We can look through the concat when lowering them:
  shuffle(concat(v1, v2), undef)
->
  concat(VZIP(v1, v2):0, :1)

This lets us generate the native shuffles instead of scalarizing to
dozens of VMOVs.
