For a Variant II architecture, the TP offset of a TLS symbol is st_value -
tlsoffset + r_addend. tlsoffset is computed by either calculate_tls_offset
or calculate_first_tls_offset.
The return value of calculate_first_tls_offset is the smallest integer
satisfying res >= size and (-res) % p_align = p_vaddr % p_align
(= p_offset % p_align). (The formula is a bit contrived. The basic idea
is to subtract the minimum integer from size + align - 1 so that the result
ihas the expected remainder.)
