At least in ELF, alignment values are represented not by exponents but by
just numbers in files, so we convert them back and force. "Alig...

[LLVMdev] LLD: representation of a power of two value
I submitted a series of patches to convert all uses of log2 values to
non-log2 values (That was harder than I thought because the types of the
two are the same. They only different in meaning. So it was not easy to
distinguish them. I split up patches so that anyone can verify correctness
of the conversion that I've done.)

[LLVMdev] LLD: representation of a power of two value
It's not a big deal, but it always annoyed me a bit when I hit it, so I'll
bring it up here.
LLD represents an alignment X as log2(X) in some places and just X in other
places. It's a bit confusing. Because I always think alignments in my mind
in terms of 1, 2, 4, 8, ..., instead of 2^1, 2^2, 2^3, ..., I'd like to
propose to always use real values.
Any objections?
