This series introduces limited support for R5900 multimedia instructions
(MMIs) by implementing and testing PCPYLD, PCPYUD, LQ and SQ.
32 128-bit multimedia registers (MMRs) are introduced. They are split into
two 64-bit halves: the lower halves are the GPRs and the upper halves are
accessible by the R5900-specific multimedia instructions.
The MMIs are only available with TARGET_MIPS64 since 64-bit GPRs are
required.
The relation between SQ and RDHWR may need to be revisited. I'm hoping to
discuss the details with Maciej.
This series has been successfully built with the 10 different build
configurations
{gcc,clang} x -m64 x mips{,64}el-{linux-user,softmmu}
{gcc,clang} x -m64 x mipsn32el-linux-user
