  Allow optimization of __size_returning_new variants. (#102258)

https://github.com/llvm/llvm-project/pull/101564 added support to TLI to
detect variants of operator new which provide feedback on the actual
size of memory allocated (http://wg21.link/P0901R5). This patch extends
SimplifyLibCalls to handle hot cold hinting of these variants.
