07c1c9ebc7 MIPS: small test-case fix for chaining of fixup position.
Add nops to the branch-delay slots of the 'beq' and 'bne' instructions
used in the test-case. Having a branch instruction in the branch-delay-slot
of another branch is undefined on mips.

In regular code we avoid this by using the Branch() macro-instruction which
fills the branch-delay-slot with nop() automatically, unless the programmer
asks to use it (via USE_BRANCH_DELAY).

There is more info about branch-delay-slots on this page, and in the ISA
reference also on the page:

4084e698c3 Fixed a bug in the chaining of fixup position
The ARM and MIPS assemblers had a bug where they did not handle the last element
in the list of code positions correctly during the fixup of offsets for forward
jumps. This happened when the first instruction contained a forward jump to a
label, and that label was used in a forward jump later, too.

Unified the code for Assembler::next on ARM and MIPS while we were there.

Added test cases, even for ia32/x64, which seem to be correct, even I don't
fully understand why... %-}

2531480d10 Re-establish mips basic infrastructure.
This commit adds current working versions of assembler, macro-assembler,
disassembler, and simulator.

All other mips arch files are replaced with stubbed-out versions that
will build.

Arch independent files are updated as needed to support building and
running mips.

The only test is cctest/test-assembler-mips, and this passes on the
simulator and on mips hardware.

26a8dc3818 ARM: Make the ARM hardware builder green
Fix a bug in the --debug-code alignment check in the C entry stub.

Don't force the --debug-code flag in the ARM disassembler tests. The framework does support passing flags and the test runner will when running tests in debug mode.

Skip some deserialization tests which crashes from time to time.

Mads, please just have to look at the new flag --disable-native-files (two files not in the mips directory).

a6a7c75ae0 MIPS port initial commit
This is the first step in the MIPS port of V8. It adds assembler, disassembler and simulator for the MIPS32 architecture.

Contains stubbed out implementation of all the compiler/code generator infrastructure to make it all build.
