Many components under stand/ had CLANG_NO_IAS added when Clang's Integrated Assembler (IAS) did not handle .codeNN directives. Clang gained support quite some time ago, and we can now build stand/ with IAS. In most cases IAS- and GNU as-assembled boot components were identical, and CLANG_NO_IAS was already removed from other components. Clang IAS produces different output for some components, including cdboot, so CLANG_NO_IAS was not previously removed for those. In the case of cdboot the difference is that IAS adds a size override prefix (67h) to many instructions to specify a 32-bit address, even though the two high bytes are zero. This wastes three bytes per instance, but as cdboot is not size-constrained it doesn't matter. Padding is also different in one case; Clang used two one-byte nops while GNU as used a single two-byte xchg %eax, %eax. In any case, there is no functional change.
