Branch: master

Fix more bugs in AArch64 simulator.
* cpustate.c (aarch64_set_reg_s32): New function.
(aarch64_set_reg_u32): New function.
(aarch64_get_FP_half): Place half precision value into the correct
slot of the union.
(aarch64_set_FP_half): Likewise.
* cpustate.h: Add prototypes for aarch64_set_reg_s32 and
aarch64_set_reg_u32.
* memory.c (FETCH_FUNC): Cast the read value to the access type
before converting it to the return type. Rename to FETCH_FUNC64.
(FETCH_FUNC32): New macro. Duplicates FETCH_FUNC64 but for 32-bit
accesses. Use for 32-bit memory access functions.
* simulator.c (ldrsb_wb): Use sign extension not zero extension.
(ldrb_scale_ext, ldrsh32_abs, ldrsh32_wb): Likewise.
(ldrsh32_scale_ext, ldrsh_abs, ldrsh64_wb): Likewise.
(ldrsh_scale_ext, ldrsw_abs): Likewise.
(ldrh32_abs): Store 32 bit value not 64-bits.
(ldrh32_wb, ldrh32_scale_ext): Likewise.
(do_vec_MOV_immediate): Fix computation of val.
(do_vec_MVNI): Likewise.
(DO_VEC_WIDENING_MUL): New macro.
(do_vec_mull): Use new macro.
(do_vec_mul): Use new macro.
(do_vec_MLA): Read values before writing.
(do_vec_xtl): Likewise.
(do_vec_SSHL): Select correct shift value.
(do_vec_USHL): Likewise.
(do_scalar_UCVTF): New function.
(do_scalar_vec): Call new function.
(store_pair_u64): Treat reads of SP as reads of XZR.
