b4942eb3a3 Reland "[ic] Fix handling of API properties with side effects"
This is a reland of 0ce36e7d0e

The reland includes two fixes:
- Move the EvaluateGlobalForTesting into libv8 to avoid linkage issues
  and to avoid having to export ThreadLocalTop symbols.
- Give the ExecutionMode enum a uint8_t backing type to avoid endianess
  issues.

This new optional parameter controls whether "Runtime.evaluate" ignores
break points and previous "Debugger.pause" calls while evaluating the
expression. This will be used for live expressions, which should never
interfere with debugging.

41719a42ac Restrict GeneratePreagedPrologue to proper functions.
This solves a bug discovered with fast accessors, where a pre-age prologue
was written into a stub. Since StaticMarkingVisitor<.>::IsFlushable will
only flush Code::FUNCTION [1], we'll restrict GeneratePreagedPrologue to
functions, too, instead of adding a Code::STUB restriction.

Also, generalize api accessor test cases to --optimize-for-size.
Also, fix CompilationCacheCachingBehavior for --optimize-for-size.
