By calling getScalarizationOverhead with the CallInst instead of the types of
its arguments, we make sure that only unique call arguments are added to the
scalarization cost.
getScalarizationOverhead() is extended to handle calls by only passing on the
actual call arguments (which is not all the operands).
This also eliminates a wrapper function with the same name.

Previously this test case fired an assertion in getNode because we tried to create an insert_subvector with both input types the same size and the index pointing to half the vector width.

The primary use of the dump() functions in LLVM is for use in a
debugger. Unfortunately lldb does not seem to handle default arguments
so using `p SomeMI.dump()` fails and you have to type the longer `p
SomeMI.dump(nullptr)`. Remove the paramter to make the most common use
easy. (You can always construct something like `p
SomeMI.print(dbgs(),MyTII)` if you need more features).

Replaces an xor+movd/movq with an xorps which will be shorter in codesize, avoid an int-fpu transfer, allow modern cores to fast path the result during decode and helps other combines recognise an all-zero vector.
The only reason I can think of that we'd want to keep scalar_to_vector in this case is to help recognise the upper elts are undef but this doesn't seem to be a problem.

While this probably should be considered a dump debugger utility, the C
API currently has no other ways to print a module to stderr for error
reporting purposes, so keep it even in release builds.

Support lowering AEABI TLS access (__aeabi_read_tp) with long calls.
This requires adjusting the call sequence to use an indirect call to get
full addressability.

PACKUSWB converts Signed word to Unsigned byte, (the same about DW) and it can't be used for umin+truncate pattern.
AVX-512 VPMOVUS* instructions fit the pattern since they convert Unsigned to Unsigned.

formatting that has evolved here over the past years prior to making
somewhat invasive changes to thread new PM support through the business
logic.

This arranges the static helpers in an order where they are defined
prior to their use to avoid the need of forward declarations, and
collect the core pass components at the bottom below their helpers.
This also folds one trivial function into the pass itself. Factoring
this 'runImpl' was an attempt to help porting to the new pass manager,
however in my attempt to begin this port in earnest it turned out to not
be a substantial help. I think it will be easier to factor things
without it.
This is an NFC change and does a minimal amount of edits over all.
Subsequent NFC cleanups will normalize the formatting with clang-format
and improve the basic doxygen commenting.

Summary:
Adds the following instructions:
* mfpmr
* mtpmr
* icblc
* icblq
* icbtls
Fix the scheduling for mtspr on e5500, which uses CFX0, instead of
SFX0/SFX1 as on e500mc.
Addresses PR 31538.

The type system already requires that the number of vector elements must fit in 32-bits so an index should as well. Even if the type of the index were larger all we care about is that the constant index can fit in 64-bits so that we can call getZExtValue.

Most flags were already initialized by the TargetOptions constructor but
we missed out on one. Also, simplify the constructor by using field
initializers when possible.

appendCallAsync, which all RPC call functions ultimately build on, will call
abandonAllPendingResponses on channel error. These extra calls are redundant.

The matching code tries to canonicalize XOR to the left, but if there are two XORs and only one is a vnot, this canonicalization can prevent matching.

The jumbled scalar loads will be sorted while building the tree and these accesses will be marked to generate shufflevector after the vectorized load with proper mask.
