68d5f916d8 Fix build on solaris platforms 
e8b9f2d7 introduced a different cast which broke building on Illumos.
Revert to previous behavior for V8_OS_SOLARIS only.

Found on SmartOS while building with gcc 4.9.0.

edit1: adding jochen to reviewers since he was assigned through the issue tracker and danno since he seems to do a fair amount of cross-platform work

edit2: removing BUG reference because I don't understand what LOG needs to contain (and it seems to link to chromium and not the v8 repo). Please edit commit message as appropriate.

b97df83752 Use Rotate*() functions instead of doing this manually. 
Shouldn't make a difference in practice, but it's a bit more readable and it
gets the case of a 0 shift correct without undefined behavior.

a6f5fca5e6 Fix preparing log file name. 
Problem:
Excuting with flags as "--prof --logfile-per-isolate --logfile=/path/to/filename"
expected file name: /path/to/isolate-<isolate id>-filename
current result: isolate-<isolate id>-/path/to/filename

This patch makes the file name we expected.

f1ba8d8f86 Contribution of PowerPC port (continuation of 422063005) - AIX Common1 
Contribution of PowerPC port (continuation of 422063005 and 817143002). This patch covers
the key changes needed to the common files needed to support AIX. Subsequent
patches will cover:
- changes to update the ppc directories so they are current with the changes
in the rest of the project.
- remaining AIX changes not resolved by 4.8 compiler
- individual optimizations for PPC

f4fb702569 Make FlushICache NOP for Nvidia Denver CPU's. 
Denver supports a coherent cache mechanism. There is no need to clean
the D cache and invalidate I cache. MTS has to check the translation
anytime there is an I cache invalidate and this time can be saved by
making FlushICache a NOP.

The patch improves Octane by roughly 3-4% on Denver.

71bb00e261 Consistently use only one of virtual/OVERRIDE/FINAL. 
FINAL implies OVERRIDE, which in turn implies virtual, so there's no need to use
more than one of these. The Google C++ style guide even requires this, see
http://google-styleguide.googlecode.com/svn/trunk/cppguide.html#Inheritance.

While we're here, port r24662 to x87.

The net result is that v8 compiles again with a current clang.

Considering that g++0x implies newer compiler, there should not be the

 SMMLS r, b, c, a

computes

 r = ((a << 32) - b * c) >> 32

while the documentation is kinda misleading and states that it should
compute

 r = a - ((b * c) >> 32)

The actual behavior is kinda useless, so we drop the instruction again.
