This change plumbs import assertions from SourceTextModuleDescriptor's ModuleRequestMap into SourceTextModuleInfo via a new ModuleRequest type, where previously there had been only the specifier. SourceTextModuleDescriptor::module_map now deduplicates module requests using the specifier and the import assertions. Continuing to use the specifier alone would cause a loss of information in the event that a module imports from the same specifier multiple times using different sets of assertions. Failing to deduplicate at all would result in multiple requests for statements like `import {a,b,c} from "foo.js"`, which would be a potential performance issue. See design doc at https://docs.google.com/document/d/1yuXgNHSbTAPubT1Mg0JXp5uTrfirkvO1g5cHHCe-LmY for more detail on this decision. v8::internal::ModuleRequest holds the assertions as an array of the form [key1, value1, position1, key2, value2, assertion2, ...]. However the parser still needs to use a map, since duplicate assertion keys need to be detected at parse time. A follow-up change will ensure that assertions are sorted using a proper lexicographic sort.

This CL splits the class definitions per .tq file, to realize the following relationship: A class defined in src/objects/foo.tq has a C++ definition in src/objects/foo.h. Torque then generates: - torque-generated/src/objects/foo-tq.inc An include file (no proper header) to be included in src/objects/foo.h containing the Torque-generated C++ class definition. - torque-generated/src/objects/foo-tq-inl.inc An include file (no proper header) to be included in src/objects/foo-inl.h containing inline function definitions. - torque-generated/src/objects/foo-tq.cc A source file including src/objects/foo-inl.h that contains non-inline function definitions. Advantages of this approach: - Avoid big monolithic headers and preserve the work that went into splitting objects.h - Moving a definition to Torque keeps everything in the same place from a C++ viewpoint, including a fully Torque-generated C++ class definition. - The Torque-generated include files do not need to be independent headers, necessary includes or forward declarations can just be added to the headers that include them. Drive-by changes: A bunch of definitions and files had to be moved or created to realize a consistent 1:1 relationship between .tq files and C++ headers.
