Changes since v2:
* Update against master(v2.8.0-rc1)
* Tested on Loongson as mips32r2(el) and mips64r2(el) hosts.
Loongson only implements little-endian mips32/mips64 ISA.
* Fully work for 32-bit and 64-bit guests.
Fix two bugs：segmentation fault on mips64el with 32-bit guests,
blocking when emulating i386 kernel on mips64el.
* Fix some minor style problems.
* PATCH v2 12~16 are not examined due to the lack of R6 machine.
To be tested:
* big-endian mips32 and mips64 hosts.
I have tried running qemu-system-mips on an X86. The speed is awful.
The compilation of qemu did not complete over a night until I gave up.
A better way is needed to do this test.
* MIPS R6.
