[MIPS] When calculating a relocation using an undefined weak symbol don't check for overflow.
In MIPS the relocation calculation only ignores the overflow checks for undefined

the relocations used by the: b* instructions; pc/gp relative symbol offsets; and the
lwpc/ldpc MIPS r6 instructions.

Fix corrupted .eh_frame section with LTO and --gc-sections.
Backport from trunk:
When --gc-sections is turned on during an LTO link, the .eh_frame sections
from deferred files are processed before those from the replacement files.
As a result, the section end-cap from crtendS.o is placed ahead of
the .eh_frame data from the replacement files. This patch fixes the bug
by skipping the layout of the deferred sections during GC pass 2.
