Currently, we context allocate all parameters for generators.
With this CL, we keep arguments on stack (unless they escape to inner
closure) and copy them between the stack and the generator's register
file on suspend/resume. This will save context allocation in most cases.
Note: There is an asymmetry between suspend and resume.
- Suspend copies arguments and registers to the generator.
- Resume copies only the registers from the generator, the arguments
are copied by the ResumeGenerator trampoline.

This CL uses the new function pointers and generic features of Torque
to improve the performance of TypedArray.p.sort.
Instead of one Load/Store builtin that dispatches at runtime based on
the element kind, there are now many small builtins (one for each
element kind). The sorting algorithm then uses function pointers to
those small builtins, which get set once.

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.

Currently ProfilerListener holds all the CodeEntries it ever
created during the profiling session. It is not capable of removing
entries corresponding to the code objects discarded by GC as there's
no such code event.
However it is sometimes possible to tell if a code object was GCed.
Hook up to the CodeMap code entry removal and if the entry has never
been hit by a sample we can safely delete it.
As a bonus the CodeEntryInfo size has been reduced on x64, which also
saves 8 x <number of code entries> bytes.
