[PATCH] D27613: [ELF] - Change now -Ttext/-Tdata/-Tbss works.

Previously user was unable to set -Ttext=0x0 for example,
it is PR31295. Result was a crash because of wrong calculation of file offsets offsets.
bfd sets the section address in that case, gold the segment address.

Patch implements bfd behavior, it places sections specified by -T* to be first in the load.
That way we can start assinging addresses from their VA and do not intersect with other sections.
Testcase shows what I mean.
