This CL adds fuzzers for the wasm module sections 'types', 'names',
'globals', 'imports', 'function signatures', 'memory', and 'data', one
fuzzer per section. No fuzzers are added for the other sections because
either there already exists a fuzzer (e.g. wasm-code), or there exist
inter-section dependencies.
To avoid introducing a bunch executables which would make compilation
with make slow, I introduce a single executable
'v8_simple_wasm_section_fuzzer' which calls the fuzzers mentioned above.
This executable is run by the trybots and ensures that the fuzzers
actually compile. For debugging I introduce commandline parameters which
allow to execute the specific fuzzers from 'v8_simple_wasm_section_fuzzer'.

The wasm-module-runner is used both in cctests and in fuzzers. As
discussed offline, it is weird to include cctest header files in
fuzzers, so I introduce a new test/common directory which contains the
common files.

With this CL the wasm-code-fuzzer first decodes and interprets the test
case generated by the fuzzer. It then compiles the test case, but only
executes the compiled instance if the interpretation of the test case
was successful. If the compiled instance is executed, then the result of
the execution is compared with the result of the interpretation.
Additionally this CL refactors the CompileAndRunWasmModule function in
wasm-module.cc to resuse code in the call to the interpreter.

This adds the v8-side fuzzer executables for smoke testing.
This also renames the old gyp targets to stay consistent
with chromium.
Naming convention for type X after the rename:
library: X_fuzzer (gn), X_fuzzer_lib (gyp)
executable v8: v8_simple_X_fuzzer
executable chromium: v8_X_fuzzer

This prepares for pulling chromium's build as dependency for
gn. After this, the files in build and gypfiles need to stay
in sync until chromium is updated.

This will allow to pull in gyp as a deps to the same location
as chromium (tools/gyp not build/gyp), needed for gn switch.
This is the first step of a 3-way move.
1) Copy v8.gyp in v8
2) Update references in embedders (follow up)
3) Remove old v8.gyp (follow up)
