Split out "Raw Cmm" dump to its own flag -ddump-raw-cmm Previously, -ddump-cmmz was used to dump out the "Raw Cmm" right before it gets passed to the backends, as well as all of the intermediate phases in the new code generator. Unfortunately, there are a lot of intermediate phases, which means -ddump-cmmz takes a very long time with -fnew-codegen for large programs, even if you're only interested in the final result. Here we split up -ddump-cmmz into -ddump-cmmz (now exclusively for the new code generator) and -ddump-raw-cmm (for both code generation paths.) The old flag was not documented in the manual, so hopefully not too many people will be surprised by this change.

Change how we compute install paths on cygwin We used to have MK_INSTALL_DEST = "$(shell cygpath $1)" but this meant we ended up with "$(shell cygpath "[...]/html/`basename $$i`")" and the $(...) gets evaluated before the makefile rule, so the for loop hasn't been run, and so $i isn't defined. So we were taking the basename of the empty string, meaning docs weren't being installed in the right place. Now we have MK_INSTALL_DEST = $$(cygpath $1) so the evaluation happens in the shell, while the for loop is running.
