The WASM spec maximum memory size is higher than internal V8 maximum object
size. When a memory object grows above this limit (and only in that case), we
should signal an error.

This worked for not-exported memory; however when growing exported memory, the
code was comparing the V8 memory limit with the maximum number of pages defined
in the module, instead of the current number of pages + the number of new
required pages. This lead to signaling errors even when growing exported memory
below the V8 limit if the maximum number of pages specified in the module was
higher than the V8 limit.

GrowMemoryBuffer already checks that we do not grow a memory buffer past the
maximum size specified as parameter, so we can pass it the minimum between the
the V8 limit and the maximum number of pages specified in the module.

This CL introduces a test in test/mjsunit/wasm/import-memory.js that triggers
the problematic path and a patch to fix it.

Removes the Compiler::CompileDebugCode and Compiler::EnsureBytecode functions
and replaces them with a Compiler::Compile(Handle<SharedFunctionInfo> shared)
function. The code in compiler.cc is refactored to use this function to compile
the SharedFunctionInfo when compiling a JSFunction.

Also does some other cleanup:
 - Removes CompileUnoptimizedFunction and inlines into new Compiler function
 - Moves code to create top level SharedFunctionInfo into CompilerTopLevel and
   out of FinalizeUnoptimizedCompile.

In graph building, use liveness information to only create Phis

The accumulator should never be alive when jumping back to a loop
header, or jumping out of a loop. This means that as far as far as
TurboFan is concerned, we never need to create Phis or LoopExitValues
for the accumulator, as its value should not escape the loop.

For safety, this also augments the IsLivenessValid DCHECK in the
liveness analysis to check that the accumulator is not live in these
cases, and amends the bytecode analysis tests to kill the accumulator
where necessary to ensure this.

As a drive-by, added some comments to the more complex bytecode analysis
tests, since figuring out what they were for and how to fix them took a
non-trivial amount of time.

FPRegister <-> FPRegister moves and swaps were implemented using the FMOV
instruction, whatever the size of the register. However, FMOV only supports
Float and Double moves, it cannot move a whole 128bit register.

Instead, use the vector MOV instruction:

- Simd128 move:      mov vd.16b, vn.16b
- Float/Double move: mov vd.8b, vn.8b
