Avoid cast alignment warning in cache string view

The cache allocates strings as

    uint16_t size;
    char content[];
    char zero;

Aligned to the uint16_t. When doing the casting, this causes a
warning on some architectures that cannot do unaligned loads, such
as armhf.

Use __builtin_assume_aligned() to explictly say that the pointer
is aligned to 16 bits. This is a bit of a backhanded approach,
as the warning seems to be actually avoided by the function
returning a void* rather than the assumed alignment, but this
is very much self-documenting.
