3d1a17c2ac Update tests to use the new compilation API + related fixes. 
Esp. get rid of PreCompile in tests, as it's going to be removed.

Notes:
- The new compilation API doesn't have a separate precompilation phase, so there
is no separate way to check for errors except checking the compilation
errors. Removed some tests which don't make sense any more.
- test-api/Regress31661 didn't make sense as a regression test even before the
compilation API changes, because Blink doesn't precompile this short scripts. So
detecting this kind of errors (see crbug.com/31661 for more information) cannot rely
on precompilation errors.
- test-parsing/PreParserStrictOctal has nothing to do with PreParser, and the comment
about "forcing preparsing" was just wrong.
- test-api/PreCompile was supposed to test that "pre-compilation (aka
preparsing) can be called without initializing the whole VM"; that's no longer
true, since there's no separate precompilation step in the new compile
API. There are other tests (test-parsing/DontRegressPreParserDataSizes) which
ensure that we produce cached data.
- Updated tests which test preparsing to use PreParser directly (not via the
 preparsing API).
- In the new compilation API, the user doesn't need to deal with ScriptData
ever. It's only used internally, and needed in tests that test internal aspects
(e.g., modify the cached data before passing it back).
- Some tests which used to test preparse + parse now test first time parse +
  second time parse, and had to be modified to ensure we don't hit the
  compilation cache.

3eb418df78 Fix fixed-point vcvt_f64_s32 immediate value encoding 
The (32 - fraction_bits) value should be encoded so that the least
significant bit is set to bit 5 and the four next bits to bits 0-3. Fix
the previously incorrect encoding. This bug did not cause behavioral
issues before, since in existing uses of the function the order of the
bits in the immediate value does not matter, as they are all 1.

c21cf2d334 Function calls are handled with a LoadIC and a FunctionCallStub. This works well, but we can create a platform to gather custom feedback by inventing a CallIC. CallIC takes a JSFunction as input, maintains UNINIT/MONO/MEGA state in a feedback slot, and engages in limited patching for the most efficient code. 
The change creates a degrade in NBody tests, but a follow-on CL addresses it by using this custom feedback platform to give a 45% improvement.

0b53ed2d2b Check in Lithium that allocation size in Smi range. 
This is to avoid triggering an assertion from Smi::FromInt. The
generated code is unreachable, so it is not a real bug.

d21acd91e9 ARM64: Fix and improve atomic operations. 
* The 'compare and swap' operations should enforce memory ordering even when
  the exchange does not occur.

* The exclusive monitor does not need to be cleared by CLREX if a LDRX was
  not followed by a matching STREX.

* Use LDAR and STLR where possible.

* Use the 'I' and 'J' constraints to hint for constants valid for immediate
  values.
