This CL is to mitigate R_X86_64_PC32 relocation overflow problems for huge binaries that has near 2G allocated sections.
By examining those binaries, I found these 2 issues contributes to the problem:
1). huge ".dynsym" and ".dynstr" stands in the way between .rodata and .text
2). _init_array_start/end are placed at 0 if no ".init_array" presents, this causes .text relocation against them become more prone to overflow.
This CL addresses 1st problem (the 2nd will be addressed in another CL.) by assigning a smaller sortrank to .dynsym and .dynstr thus they no longer stand in between
Note: this CL affects multiple tests, I include in this CL only 2 of many changes to the tests. And I'll provide the rest once this main part of this CL gets approved.
