Migration to IR PGO
https://bugs.webkit.org/show_bug.cgi?id=308827
rdar://171380240
Reviewed by Ryan Reno.
Currently WebKit PGO is using frontend instrumentation enabled by
CLANG_INSTRUMENT_FOR_OPTIMIZATION_PROFILING which passes
-fprofile-instr-generate
to the compiler invocation. Migration to IR PGO gives a nice performance
progression across WebKit, WebCore, and JSC; general score progression on
benchmarks.
