Pull request overview

Removes the InlineCandidateInfo::exactContextNeedsRuntimeLookup field and the corresponding impMarkInlineCandidate / impMarkInlineCandidateHelper parameter, simplifying the JIT inlining candidate plumbing now that the flag is no longer consumed.

Changes:

• Drop InlineCandidateInfo::exactContextNeedsRuntimeLookup from the inline candidate info struct.
• Remove the exactContextNeedsRuntimeLookup parameter from impMarkInlineCandidate and impMarkInlineCandidateHelper.
• Update all call sites to the new impMarkInlineCandidate signature.

• This comment references exactContextNeedsRuntimeLookup, but that field/parameter was removed in this PR, so the note is now stale and misleading.

        // Note exactContextNeedsRuntimeLookup is reset later on,
        // over in impMarkInlineCandidate.
