Rafal Kolanski f473021686 aarch32: tune user_context struct for verification ...

Verification requires packed structures for reasoning (no implicit
padding).

The FPU context starts with 64-bit words, which the C parser assumes
have 8-byte alignment. Unfortunately, for this version of the kernel,
aarch32 has an odd number of word_t (32-bit) registers, resulting in an
extra word of implicit padding.

This type of manual padding is naturally fragile and will break as soon
as a user register is added or removed from the user context.
