Reapply [IR] Avoid creating icmp/fcmp constant expressions (#92885)
Reapply after https://github.com/llvm/llvm-project/pull/93548,
which should address the lldb failure on macos.
-----
Do not create icmp/fcmp constant expressions in IRBuilder etc anymore,
i.e. treat them as "undesirable". This is in preparation for removing
them entirely.

[MSAN] Pass Origin by parameter to __msan_warning functions
Summary:
Normally, the Origin is passed over TLS, which seems like it introduces unnecessary overhead. It's in the (extremely) cold path though, so the only overhead is in code size.
But with eager-checks, calls to __msan_warning functions are extremely common, so this becomes a useful optimization.
This can save ~5% code size.

[NewPM] Port Msan
Summary:
Keeping msan a function pass requires replacing the module level initialization:
That means, don't define a ctor function which calls __msan_init, instead just
declare the init function at the first access, and add that to the global ctors
list.
Changes:
- Pull the actual sanitizer and the wrapper pass apart.
- Add a newpm msan pass. The function pass inserts calls to runtime
library functions, for which it inserts declarations as necessary.
- Update tests.
Caveats:
- There is one test that I dropped, because it specifically tested the
definition of the ctor.
