Jeremy Faller 9ae8f71c94 [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.
