target-arm: Fix warn about implicit conversion
Clang warns about an implicit conversion as follows:
/mnt/devops/code/qemu/target-arm/neon_helper.c:1075:1: warning: implicit conversion from 'int' to 'int8_t' (aka 'signed char') changes value from 128 to -128 [-Wconstant-conversion]
NEON_VOP_ENV(qrshl_s8, neon_s8, 4)

dest = (1 << (sizeof(src1) * 8 - 1)); \
~ ~~^~~~~~~~~~~~~~~~~~~~~~~~~
Fix it by casting to appropriate type.
