LLD ignores --high-entropy-va when linking 32 bit binaries but LD apparently throws the error.

Force pushed to enable high entropy only on 64 bit targets.

Looks good but I don't know who would be the right reviewer here.
There are 2 weeks to beta so I think it would be nice if this landed soonish and was reverted for beta so we have more than 6 weeks of testing here.

FWIW LLD recently enabled ASLR by default and Binutils followed.

I am inclined to just land this -- certainly seems like an improvement.

I agree that getting this tested for longer would be good; we can let it land in 1.50 (as opposed to 1.49) for example, though I am likely to forget about this by the time we promote master to beta in ~5 weeks.
