835a55e7f3 POWER: Add support for the Power ISA
This adds support for the 32-bit, big endian Power ISA. This supports both
integer and floating point instructions based on the Power ISA Book I v2.06.

56154cff5e Enable getuid and getgid related syscalls on X86_SE
I've tested these on x86 and they work as expected.

In theory for 32-bit x86 we should have some sort of special
handling for the legacy 16-bit uid/gid syscalls, but in practice
modern toolchains don't use the 16-bit versions, and m5 sets the uid
and gid values to be less than 16-bits anyway.

This fix is needed for the perl spec2k benchmarks to run.

22dc2b5595 Ignore rt_sigaction() syscalls on x86 and x86_64
This is currently how alpha handles this syscall.

This is needed for the gcc spec2k benchmarks to run.

30a185dcd0 Hook up the munmap() syscall for 32-bit x86.
This is straightforward, as munmapFunc() doesn't do anything.
I've tested it with code running munmap() just in case.

9a8cb7db7e python: Move more code into m5.util allow SCons to use that code.
Get rid of misc.py and just stick misc things in __init__.py
Move utility functions out of SCons files and into m5.util
Move utility type stuff from m5/__init__.py to m5/util/__init__.py
Remove buildEnv from m5 and allow access only from m5.defines
Rename AddToPath to addToPath while we're moving it to m5.util
Rename read_command to readCommand while we're moving it
Rename compare_versions to compareVersions while we're moving it.

6e97feb8a5 X86: Make not taken conditional moves leave the destination alone. Adjust CMOVcc.
The manuals from both AMD and Intel say that when writing to a 32 bit
destination in 64 bit mode, the upper 32 bits of the register are filled with
zeros. They also both say that the CMOV instructions leave their destination
alone when their condition fails. Unfortunately, it seems that CMOV will zero
extend its destination register whether or not it was supposed to actually do
a move on both platforms. This seems to be the only case where this happens,
but it would be hard to say for sure.

3a55fc5cac X86: Implement shift right/left double microops.
This is my best guess as far as what these should do. Other existing microops
use implicit registers, mul1s and mul1u for instance, so this should be ok.
The microop that loads the implicit DoubleBits register would fall into one
of the microop slots for moving to/from special registers.

e2e0ae576a X86: Make sure immediate values are truncated properly.
Register values will be "picked" which will assure they don't have junk beyond

we should truncate them explicitly.
