cmd/compile: static composite literals are side-effect free
This extends CL 22192.
This removes the remaining performance disparity
between non-SSA and SSA on the AppendInPlace benchmarks.
Going from non-SSA to SSA:
AppendInPlace/NoGrow/2Ptr-8 1.60µs ± 5% 1.53µs ± 5% -4.04% (p=0.000 n=15+14)
AppendInPlace/NoGrow/3Ptr-8 2.04µs ± 3% 1.96µs ± 2% -3.90% (p=0.000 n=13+14)
AppendInPlace/NoGrow/4Ptr-8 2.83µs ± 8% 2.62µs ± 4% -7.39% (p=0.000 n=13+15)
Previously these were 20% regressions.
