59ae9d9ac9 runtime: TestGcSys: if GOGC=off, skip instead of failing

54dffda2b6 runtime: prevent garbage collection during hashmap insertion 
Inserting a key-value pair into a hashmap storing keys or values
indirectly can cause the garbage collector to find the hashmap in
an inconsistent	state.

Fixes #5074.

46890f60ce runtime: move TestGcSys into a separate process 
Fixes #4904.
The problem was that when the test runs the heap had grown to ~100MB,
so GC allows it to grow to 200MB, and so the test fails.
Moving the test to a separate process makes it much more isolated and stable.

85266dfd4d runtime: relax TestGcSys 
This fixes occasional 64-bit failures.
Maybe it will fix the 32-bit failures too,
so re-enable on 32-bit for now.

244706bd0f runtime: disable memory profiler in gc_test 
This lets the test pass on PPC64 GNU/Linux, which uses a much
larger page size and thus uses more memory to hold blocks
allocated for memory profiling.

2a6e6999a4 runtime, time: accelerate tests in short mode. 
before   after
go test -short time                4.144s  1.215s
go test -short runtime             1.315s  0.351s
go test -short -cpu=1,2,4 runtime  4.376s  1.266s

Partially solves issue 3015.

842c906e2e 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.

26239417bb runtime: Make gc_test test extra allocated space, not total space. 
Testing total space fails for gccgo when not using split
stacks, because then each goroutine has a large stack, and so
the total memory usage is large.

4e7aac5413 reflect: make unsafe use of SliceHeader gc-friendly 
Revert workaround in compiler and
revert test for compiler workaround.

Tested that the 386 build continues to fail if
the gc change is made without the reflect change.
