[Inline] prevent inlining on noprofile mismatch
Similar to
commit bc044a88ee3c ("[Inline] prevent inlining on stack protector mismatch")
The noprofile function attribute is meant to prevent compiler
instrumentation from being inserted into a function. Inlining may defeat
the developer's intent. If the caller and callee don't either BOTH have
the attribute or BOTH lack the attribute, suppress inline substitution.
This matches behavior being proposed in GCC:
https://gcc.gnu.org/pipermail/gcc-patches/2021-June/573511.html
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80223
Add LangRef entry for noprofile fn attr, similar to text added in D93422
and D104944.
