[JSC] Install approximate FTL bytecode cost sooner
https://bugs.webkit.org/show_bug.cgi?id=327210
rdar://189782048
Reviewed by Tadeu Zagallo.
FTL's B3 compilation takes enough long time, but approximate FTL
bytecode cost only requires its compiled FTL node counts. So let's
record it early in BaselineJITCode so that we can use it as soon as
possible.
