The idea behind of this solution is to use the existing "relocation info" instead of consumption the CodeLinePosition events emitted by the V8 compilers.
During generation code and relocation info are generated simultaneously.
When code generation is done you each code object has associated "relocation info".
Relocation information lets V8 to mark interesting places in the generated code: the pointers that might need to be relocated (after garbage collection),
correspondences between the machine program counter and source locations for stack walking.
This patch:
1. Add more source positions info in reloc info to make it suitable for source level mapping.
The amount of data should not be increased dramatically because (1) V8 already marks interesting places in the generated code and
(2) V8 does not write redundant information (it writes a pair (pc_offset, pos) only if pos is changed and skips other).
I measured it on Octane benchmark - for unoptimized code the number of source positions may achieve 2x ('lin_solve' from NavierStokes benchmark).
2. When a sample happens, CPU profiler finds a code object by pc, then use its reloc info to match the sample to a source line.
If a source line is found that hit counter is increased by one for this line.
3. Add a new public V8 API to get the hit source lines by CDT CPU profiler.
Note that it's expected a minor patch in Blink to pack the source level info in JSON to be shown.
4.Add a test that checks how the samples are distributed through source lines.
It tests two cases: (1) relocation info created during code generation and (2) relocation info associated with precompiled function's version.

Retry: Parser & internalization fix: ensure no heap allocs during GetString(Handle<String>).
The bug has always been there: when the parser is operating in the "immediately
internalize" mode and calls GetString, we get FlatContent of a string and then
do heap allocation.
The bug was uncovered by https://codereview.chromium.org/
693803004/ (which put
the parser to the "immediately internalize" mode more often), but looking at the
code, it's possible that it can happen in other cases too.
This CL makes AstValueFactory handle this situation gracefully: it won't try to
internalize inside GetString(Handle<String>); it's unnecessary anyway since we
have the Handle<String> already.

Parser & internalization fix: ensure no heap allocs during GetString(Handle<String>).
The bug has always been there: when the parser is operating in the "immediately
internalize" mode and calls GetString, we get FlatContent of a string and then
do heap allocation.
The bug was uncovered by https://codereview.chromium.org/
693803004/ (which put
the parser to the "immediately internalize" mode more often), but looking at the
code, it's possible that it can happen in other cases too.
This CL makes AstValueFactory handle this situation gracefully: it won't try to
internalize inside GetString(Handle<String>); it's unnecessary anyway since we
have the Handle<String> already.

Handle store buffer slot overwrite during object promotion.
The bad scenario this fix handles:
We have a slot in a free list, then promote the object pointed-to by
the slot during scavenge. When allocating the space for the promoted
object, we overwrite the slot with the free list entry map if the
object is allocated just before the slot. After the allocation,
ScavengingVisitor::PromoteObject overwrites the slot with the
address of the allocated object, thus corrupting the free list.
Unfortunately, we do not have a way to construct a reliable repro
case because we would need to somehow craft a free list and store
buffer slot to be in the right configuration.

Set the FPU precision control to double-precision.
The default double precision control of FPU is extended double-precision.
While the number definition for JavaScript is double-precision. We use
the FPU control word to set the doulbe precision and replace the original
solution which store the data to memory and load it again.
This patch also fixes the error that Sunspider 1.0.2 can not run with V8 if
sse2 support is disabled.

Parser & internalizing: efficiency fixes.
1) In ParseLazy, we're already using the heap, so we can also tell
AstValueFactory to internalize immediately. This is more efficient.
2) No need to collect the values in values_ and strings_ if they're already
internalized.
3) No need to collect AstValues which are strings in values_ since they don't
need to be internalized (the underlying strings will be internalized
separately).
