This CL adds a baseline Torque implementation of the DataView getters
and setters.
Right now, the Torque code just calls the C++ implementation, which
has moved to runtime.

It is fine to use the more complex addressing modes here because our

The current profiling mode (called kLeafNodeLineNumbers in this CL)
produces a tree, with each node representing a stack frame that is seen
in one or more samples taken during profiling. These nodes refer to a
particular function in a stack trace, but not to a particular line or
callsite within that function.
This CL adds a new more (called kCallerLineNumbers) which produces a
different profile tree, where each stack trace seen during profiling,
including the line number, has a unique path in the tree.
The profile tree was previously keyed on CodeEntry*. Now it is keyed on
the pair of CodeEntry* and line_number, meaning it has distinct nodes
for those combinations which exist, and each distinct stack trace that
was sampled is represented in the tree.
For optimized code where we have inline frames, there are no line
numbers for the inline frames in the stack trace, causing duplicate
branches in the tree with kNoLineNumberInfo as the reported line number.
This will be addressed in follow-ups.

It also instantiates generic specializations when they are only used
in an assignment to a function pointer.
Example:
builtin GenericBuiltinTest<T: type>(c: Context, param: T): Object {
return Null;
}
let fnptr: builtin(Context, Smi) => Object = GenericBuiltinTest<Smi>;

This map is often quite small and holds small items (ints) so wastes
quite a bit of overhead in the backing tree representation.
This CL changes the std::map to a sorted vector of pairs. This reduces
the size significantly (2.13 MiB -> 598 KiB on the node server example).

This migrates test configs for all remaining trybots.
All migrated builders are not on CQ, hence, they don't run regularly.
Therefore, some shard configs are too low by now and are also upgraded
in this CL to match their CI counterparts.
This also sets the --gc-stress flag for all tests on gc stress builders
explicitly, since the infra-side configuration (which sets it per
builder) will be deleted soon.
