Renato Golin b451f4e376 Improve handling of stack accesses in Thumb-1 ... Thumb-1 only allows SP-based LDR and STR to be word-sized, and SP-base LDR, STR, and ADD only allow offsets that are a multiple of 4. Make some changes to better make use of these instructions: * Use word loads for anyext byte and halfword loads from the stack. * Enforce 4-byte alignment on objects accessed in this way, to ensure that the offset is valid. * Do the same for objects whose frame index is used, in order to avoid having to use more than one ADD to generate the frame index. * Correct how many bits of offset we think AddrModeT1_s has.
