Use correct modifiers on LDR instructions.

UXTW is not a valid modifier for LDR on 32-bit ARM. Compilers built
without assertions incorrectly accept the modifier, while compilers
built with assertions crash (see llvm.org/pr48805).

The intent appears to be to use the LSL modifier (and that is how the
instruction is assembled with the no-assertions compiler) so change
the code to use it.
