[vm] Add missing safepoint transitions.
...
Mostly tests; 1 non-test bug in propagating an error through Dart_SetReturnValue.
This is progress towards asserting thread->excution_state() == kThreadInVM in Object::Allocate.

[vm] Replace most runtime/vm uses of OS::Print with OS::PrintErr.
...
Leave --print-snapshot-sizes on stdout because it is parsed by Flutter benchmarks.
Replace all runtime/bin uses of OS::Print with Log::Print.

Improve the casing of Stackmap and Stacktrace.
...
- [x] Stackmap -> StackMap
- [x] Stacktrace -> StackTrace
This makes us consistent with the Dart language (StackTrace) and
corrects the casing of StackMap.

Put live register bits in stackmaps.
...
Add a count of live registers to each stackmap and add bits describing the
registers. This allows untagged values in general purpose registers at
safepoints.

Give a length field to stack bitmaps.
...
The bitmaps describing the stack have an explicit length field. It is now
an assertion failure to read bits outside the length --- they are no longer
assumed to be false.
Also remove an unused method and simplify the implementation of
BitmapBuilder by removing an embedded member that was always referred to via
a pointer.

This allows stackmaps with varying lengths in the same function, necessary

Reduce space used for stackmaps.
...
Only allocate space for the bits covered by the stackmap, instead of
for the backing store of the utility class that built it. Fix a bug
where the size in bytes was multiplied by the word size in bytes.
Also do some cleanup of the stackmap code and renaming in the tests.

Resubmit change 6302 after fixing the compiler warning on older GCC compiler versions:
...
Change 6302 description:
- Wire the stack frame iterator to use stack maps for traversing objects if
there are stack maps in the code object. If there are no stack maps it still
does the old style stack frame traversal between fp and sp looking for tagged
pointers.
- Added a mechanism to be able to iterate over the code space and look for a
particular object.
