Cherry Zhang 8ef45cf60b cmd/link: reduce the size of Reloc struct 
For linking large binaries, the slice of Relocs consumes a large
amount of memory. We can reduce this memory consumption by
shrinking the size of the Reloc struct. This CL moves the fields
used only in external linking or only on PPC64 and S390X to a
lazily initialized side struct.

Linking k8s.io/kubernetes/cmd/kube-apiserver on Linux/AMD64,
before:
inuse_space 1240.25MB total
438.11MB 35.32% 35.32%   438.11MB 35.32%  cmd/link/internal/objfile.(*objReader).readSlices

after:
inuse_space 1123.39MB total
306.85MB 27.31% 55.03%   306.85MB 27.31%  cmd/link/internal/objfile.(*objReader).readSlices

Under GOGC=5 (to simulate system under memory pressure), the max
RSS reduces from ~2.05G to ~1.83G. Even with external linking the
max RSS doesn't increase.
