They are missing a stop byte at the end.
Normally this doesn't matter, but when including a GC program
in another GC program, we strip the last byte. If that last byte
wasn't a stop byte, then we've thrown away part of the program

Make sure the side effects inside short-circuited operations (&& and ||)
happen correctly.
Before this CL, we attached the side effects to the node itself using
exprInPlace. That caused other side effects in sibling expressions
to get reordered with respect to the short circuit side effect.
Instead, rewrite a && b like:
r := a
if r {
r = b
}
That code we can keep correctly ordered with respect to other
side-effects extracted from part of a big expression.
exprInPlace seems generally unsafe. But this was the only case where
exprInPlace is called not at the top level of an expression, so I
don't think the other uses can actually trigger an issue (there can't
be a sibling expression). TODO: maybe those cases don't need "in
place", and we can retire that function generally.
This CL needed a small tweak to the SSA generation of OIF so that the
short circuit optimization still triggers. The short circuit optimization
looks for triangle but not diamonds, so don't bother allocating a block
if it will be empty.
Go 1 benchmarks are in the noise.

Currently, the pacer assumes the goal growth ratio is always exactly
GOGC/100. But sometimes this isn't the case, like when the heap is
very small (limited by heapminimum). So to placate the pacer, we lie
about the value of heap_marked in such situations.
Right now, these two lies make a truth, but GOGC is about to get more
complicated with the introduction of heap limits.
Rather than introduce more lies into the system to handle this,
introduce the concept of an "effective GOGC", which is the GOGC we're
actually using for pacing (we'll need this concept anyway with heap
limits). This commit changes the pacer to use the effective GOGC
rather than the user-set GOGC. This way, we no longer need to lie
about heap_marked because its true value is incorporated into the
effective GOGC.
