There are such tools, but they are for FPGAs. Good FPGA synthesizers
(Synplify and Leonardo) can find for example all memories even if they are
written in behavioral style and convert them to vendor macros. Some
pragmas might be needed to give some hints what kind of memory is really
wanted (distributed, block etc.). Of course you can't code with any style,
but the tools are quite good. They know things like 2-port memories etc.
Also those tools find quite funny vendor blocks from the designs sometimes
to speed up things (shift registers for example are a good example).

Unfortunately Synopsys DC doesn't support this with links to vendor
libraries and block generators. That would be fantastic feature :)
