Reland "[ARM] Stop gluing ALU nodes to branches / selects" (#118887)
Re-landing #116970 after fixing miscompilation error.
The original change made it possible for CMPZ to have multiple uses;
`ARMDAGToDAGISel::SelectCMPZ` was not prepared for this.
Pull Request: https://github.com/llvm/llvm-project/pull/118887
Original commit message:
Following #116547 and #116676, this PR changes the type of results and
operands of some nodes to accept / return a normal type instead of Glue.
Unfortunately, changing the result type of one node requires changing
the operand types of all potential consumer nodes, which in turn
requires changing the result types of all other possible producer nodes.
So this is a bulk change.

[ARMISelLowering] avoid emitting libcalls to __mulodi4()
__has_builtin(__builtin_mul_overflow) returns true for 32b ARM targets,
but Clang is deferring to compiler RT when encountering `long long`
types. This breaks sanitizer builds of the Linux kernel that are using
__builtin_mul_overflow with these types for these targets.
If the semantics of __has_builtin mean "the compiler resolves these,
always" then we shouldn't conditionally emit a libcall.
This will still need to be worked around in the Linux kernel in order to
continue to support allmodconfig builds of the Linux kernel for this
target with older releases of clang.

[ARM] Fix perf regression in compare optimization.
Fix a performance regression caused by r322737.
While trying to make it easier to replace compares with existing adds and
subtracts, I accidentally stopped it from doing so in some cases. This should
fix that. I'm also fixing another potential bug in that commit.
