Hervé Poussineau 3b67383c6c [MC][Mips] Generate required IMAGE_REL_MIPS_PAIR relocation (#120876) ...

Add the required IMAGE_REL_MIPS_PAIR relocation after
IMAGE_REL_MIPS_REFHI/IMAGE_REL_MIPS_SECRELHI

Microsoft PE/COFF specification says that the IMAGE_REL_MIPS_REFHI
relocation contains "the high 16 bits of the target's 32-bit virtual
address. [...] This relocation must be immediately followed by a PAIR
relocation whose SymbolTableIndex contains a 16-bit displacement which
is added to the upper 16 bits taken from the location being relocated."

Microsoft PE/COFF specification says that the IMAGE_REL_MIPS_SECRELHI
relocation contains "the high 16 bits of the 32-bit offset of the target
from the beginning of its section. A PAIR relocation must immediately
follow this on. The SymbolTableIndex of the PAIR relocation contains a
16-bit displacement, which is added to the upper 16 bits taken from the
location being relocated."

Behavior has been checked against Microsoft C compiler for MIPS.
