[dev.link] cmd/link: stop renumbering files for pclntab generation Creates two new symbols: runtime.cutab, and runtime.filetab, and strips the filenames out of runtime.pclntab_old. All stats are for cmd/compile. Time: Pclntab_GC 48.2ms ± 3% 45.5ms ± 9% -5.47% (p=0.004 n=9+9) Alloc/op: Pclntab_GC 30.0MB ± 0% 29.5MB ± 0% -1.88% (p=0.000 n=10+10) Allocs/op: Pclntab_GC 90.4k ± 0% 73.1k ± 0% -19.11% (p=0.000 n=10+10) live-B: Pclntab_GC 29.1M ± 0% 29.2M ± 0% +0.10% (p=0.000 n=10+10) binary sizes: NEW: 18565600 OLD: 18532768 The size differences in the binary are caused by the increased size of the Func objects, and (less likely) some extra alignment padding needed as a result. This is probably the maximum increase in size we'll size from the pclntab reworking.
