Austin Clements	196492a299	[release-branch.go1.9] runtime: map bitmap and spans during heap initialization We lazily map the bitmap and spans areas as the heap grows. However, right now we're very slightly too lazy. Specifically, the following can happen on 32-bit: 1. mallocinit fails to allocate any heap arena, so arena_used == arena_alloc == arena_end == bitmap. 2. There's less than 256MB between the end of the bitmap mapping and the next mapping. 3. On the first allocation, mheap.sysAlloc sees that there's not enough room in [arena_alloc, arena_end) because there's no room at all. It gets a 256MB mapping from somewhere lower in the address space than arena_used and sets arena_alloc and arena_end to this hole. 4. Since the new arena_alloc is lower than arena_used, mheap.sysAlloc doesn't bother to call mheap.setArenaUsed, so we still don't have a bitmap mapping or a spans array mapping. 5. mheap.grow, which called mheap.sysAlloc, attempts to fill in the spans array and crashes. Fix this by mapping the metadata regions for the initial arena_used when the heap is initialized, rather than trying to wait for an allocation. This maintains the intended invariant that the structures are always mapped for [arena_start, arena_used). Fixes #21044. Cherry-pick of CL 51714. Fixes #21234.

Austin Clements	1a6d87d4bf	[release-branch.go1.9] runtime: fall back to small mmaps if we fail to grow reservation Right now, if it's possible to grow the arena reservation but mheap.sysAlloc fails to get 256MB more of memory, it simply fails. However, on 32-bit we have a fallback path that uses much smaller mmaps that could take in this situation, but fail to. This commit fixes mheap.sysAlloc to use a common failure path in case it can't grow the reservation. On 32-bit, this path includes the fallback. Ideally, mheap.sysAlloc would attempt smaller reservation growths first, but taking the fallback path is a simple change for Go 1.9. Updates #21044 (fixes one of two issues). Cherry-pick of CL 51713. Updates #21234.

We must encode that fact in the type..namedata symbol name, to avoid incorrectly merging an unexported name with an exported name.
