cmd/compile: handle simple inlined calls in staticinit
For the cmd/go binary, this CL cuts the number of init-time allocations from about 1920 to about 1620 (a 15% reduction). #golang

A GC-friendly #golang interning cache.

A GC-Friendly Go Interning Cache
Go 1.20 is adding an interning cache for reused certificates. The entries are reference-counted with the help of the garbage collector and finalizers.

The runtime now has experimental support for memory-safe arena allocation that makes it possible to eagerly free memory in bulk. It has the potential to improve CPU performance by up to 15% in memory-allocation-heavy applications. (c)
