With the ARM instruction set, unless using Thumb, you have each instruction coded on 32 bits, so 256 assembly instructions weight 1 Kbyte.
You will need a lot more code cache than a ia32 processor to compete, probably around twice the amount.

This is not generally true. Just compare the installed sizes across architectures for e.g. http://packages.debian.org/wheezy/libc6 or http://packages.debian.org/wheezy/coreutils
