Fix uninitialized memory access (#68) 
An alternative fix is to zero the `values` and `count` fields in
JS_NewObjectFromShape() irrespective of the object's class_id but
handling it in JS_GetPropertyValue() feels cleaner.

Add fused get_loc0_loc1 opcode (#55) 
get_loc0 and get_loc1 are individually very frequent opcodes _and_ they
are very often paired together, making them ideal candidates for opcode
fusion.

Reduces microbench.js running time by about 4%.

Fix use-after-free on error during module evaluation 
E.g. if during evaluation of module A, we start loading module B and
an error occurs. This results in a call to js_free_modules() with
JS_FREE_MODULE_NOT_EVALUATED, and since module A isn't yet evaluated,
it gets freed prematurely.

To solve this we improve js_free_modules() to ensure `eval_mark` is not
set. Once js_evaluate_module() returns for module A, it will notice that
an exception occurred and call js_free_modules() with
JS_FREE_MODULE_NOT_EVALUATED. Since `eval_mark` has been cleared by then,
module A gets cleaned up as well.

67585d0421 Fix -Wimplicit-const-int-float-conversion warnings 
Compare against 0x1p63 instead of INT64_MAX. Converting INT64_MAX to
double rounds it up to INT64_MAX+1.

It made code like `if (d <= INT64_MAX) v = (int64_t)d;` behave subtly
wrong when `d >= 0x1p63` because then `v = (int64_t)d` wraps around to
a negative value.
