*	Fix libpinyin crash on ARMv7	Matias Larsson	2022-11-29	1	-4/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Fix the alignment trap in get_unigram_frequency(). Fix also other places where this same trap could happen (depending on compiler and surrounding code). The trap happened when the ARM GCC generated a SIMD instruction (specifically VLDR) to load 32 bits in a single instruction, and when the memory address was not aligned to 32 bits. VLDR traps if the address is not aligned. GCC generated the instruction because of the cast to uint32 from the address. The fix is to allocate a uint32 variable in stack and use memcpy to copy the data to that variable. This way we ensure that appropriate instructions are generated.
