a2efde46a1 [wasm] Add support for compiling WASM_INTERPRETER_ENTRY stubs
Also, add a runtime function to call the interpreter, passing a
stack-allocated buffer holding the arguments.
The WASM_INTERPRETER_ENTRY stub allocates the stack slot for the
arguments, fills it, and calls to the wasm interpreter.
It's abi is compatible with WASM functions, such that we can just
replace a call to a WASM_FUNCTION with a call to
WASM_INTERPRETER_ENTRY.
See tracking bug to get the overall picture.

e904894915 [wasm] (To|From)JSWrappers with I64 params throw a TypeError upon call.
According to the latest spec changes the WasmToJS wrapper and the
JSToWasm wrapper through a TypeError if the signature of the wrapper
contains a I64 parameter or return value. Originally the TypeError was
thrown when the parameter or return value was converted to or from JS.

In addition I removed all special handling of I64 parameters and return
values in the wrappers which was already dead code.

b2d67f3b75 [wasm] TrapIf and TrapUnless TurboFan operators implemented on mips64.
Original commit message:
[wasm] Introduce the TrapIf and TrapUnless operators to generate trap code.

Some instructions in WebAssembly trap for some inputs, which means that the
execution is terminated and (at least at the moment) a JavaScript exception is
thrown. Examples for traps are out-of-bounds memory accesses, or integer
divisions by zero.

Without the TrapIf and TrapUnless operators trap check in WebAssembly introduces 5
TurboFan nodes (branch, if_true, if_false, trap-reason constant, trap-position
constant), in addition to the trap condition itself. Additionally, each
WebAssembly function has four TurboFan nodes (merge, effect_phi, 2 phis) whose
number of inputs is linear to the number of trap checks in the function.
Especially for functions with high numbers of trap checks we observe a
significant slowdown in compilation time, down to 0.22 MiB/s in the sqlite
benchmark instead of the average of 3 MiB/s in other benchmarks. By introducing
a TrapIf common operator only a single node is necessary per trap check, in
addition to the trap condition. Also the nodes which are shared between trap
checks (merge, effect_phi, 2 phis) would disappear. First measurements suggest a
speedup of 30-50% on average.

This CL only implements TrapIf and TrapUnless on x64. The implementation is also
hidden behind the --wasm-trap-if flag.

Please take a special look at how the source position is transfered from the
instruction selector to the code generator, and at the context that is used for
the runtime call.

a3052cfe22 [compiler] Collect eager inner functions for compilation during renumbering.
This CL modifies the ast-numbering phase to collect function literals which
should be compiled eagerly. This is then used to eagerly compile the inner
functions before compiling the outer function. This will be used to queue
compilation jobs on the CompilerDispatcher in a later CL.

This CL moves the compilation of eager inner functions out of the
GetSharedFunctionInfo function and instead compiles them explicitly. This
simplifies GetSharedFunctionInfo and also means there is no need to pass a
LazyCompilationMode to the function, so this concept has been removed.
