Hans Wennborg 3740ae3b8a Revert r372893 "[CodeGen] Replace -max-jump-table-size with -max-jump-table-targets" 
This caused severe compile-time regressions, see PR43455.

> Modern processors predict the targets of an indirect branch regardless of
> the size of any jump table used to glean its target address.  Moreover,
> branch predictors typically use resources limited by the number of actual
> targets that occur at run time.
>
> This patch changes the semantics of the option `-max-jump-table-size` to limit
> the number of different targets instead of the number of entries in a jump
> table.  Thus, it is now renamed to `-max-jump-table-targets`.
>
> Before, when `-max-jump-table-size` was specified, it could happen that
> cluster jump tables could have targets used repeatedly, but each one was
> counted and typically resulted in tables with the same number of entries.
> With this patch, when specifying `-max-jump-table-targets`, tables may have
> different lengths, since the number of unique targets is counted towards the
> limit, but the number of unique targets in tables is the same, but for the
> last one containing the balance of targets.
