set up asm.js 'module'
remove irrelevant code from asm module
work towards exports
only export asm functions from asm, not library functions
export implementedFunctions when necessary for asm.js
export is reserved
fix suffix in js optimizer
notice function indentation in js_optimizer.py so that we properly scan indented code in asm.js
add asm imports and exports, hello world works
fix merge error
add asm test suite
generate separate type-specific function tables
do not allow memory growth in asm.js
function table fixes
add asm to ALL
ignore varargs in getSignature
always forward library functions
only use typed function tables in asm_js mode
export asm.js exports to outside scope
put library signatures in separate storage instead of reusing libraryFunctions
