[PatternMatch] Refactor `m_SpecificInt` to avoid constructing APInt. NFC. (#86259)
This patch passes APInt by const reference in m_SpecificInt instead of
by value. Specifically, it refactors `m_SpecificInt(uint64_t V)` to
avoid APInt construction and dangling reference.
I believe it is safe to pass the APInt by const reference into
`m_SpecificInt` even if it is a temporary.
