[LLVM] Add a check if should cast atomic operations to integer type
Currently for atomic load, store, and rmw instructions, as long as the
operand is floating-point value, they are casted to integer. Nowadays many
targets can actually support part of atomic operations with floating-point
operands. For example, NVPTX supports atomic load and store of floating-point
values. This patch adds a series interface functions `shouldCastAtomicXXXInIR`,
and the default implementations are same as what we currently do. Later for
targets can have their specialization.
