Since traps now throw real Error objects, we get stack traces
containing <WASM> functions on top-level. The additional tests check
for two traps: unreachable and memory out-of-bounds.

This extends the wasm test case which only checks the "simple"
string-variant of the stack trace.
It checks the return values of the getFunctionName, getLineNumber,
getFileName and toString methods.

Before, just a string was thrown, so no stack trace was attached there.
Generated code from wasm does not grow by this change, we just pass a
message id to the respective (new) runtime function.

This change implements switch as a balanced if/else tree or break table or
hybrid. A lot of asm.js modules are expected to extensively use switch
alongside function tables that can benefit from a better implementation.

This CL modifies the following to be LEB128:
* Function table indices
* Import table signature indices
* Export table function indices
* Function signature param count
* br/br_if break depth
* br_table target count
* block/loop expression count

Still to do:
* Import/export names (LEB128 count + inline data)
* Data segments (LEB128 offset + size + inline data)
* Function header stuff (should seperate into function sig and body sections)
* Memory access alignment + offset (still discussing)

Local declarations were previously encoded as an optional set of
4 uint16 values as part of the function declaration. This CL
implements the current design of moving these declarations to
a list of pairs of (type, count) that is part of the body.
