runtime: delete UpdateMemStats, replace with ReadMemStats(&stats).
...
Unexports runtime.MemStats and rename MemStatsType to MemStats.
The new accessor requires passing a pointer to a user-allocated
MemStats structure.
Fixes #2572 .

test: Run garbage collector before testing malloc numbers.
...
The gccgo library generates some garbage in the init routines
because it handles interfaces slightly differently. Since the
test sets MemStats.Alloc to 0, the first time the garbage
collector runs it goes negative and the test fails.
