Fix APInt::countTrailingZeros to return BitWidth if the input is zero instead of returning some random large number.

OnlyReadsMemoryFns tables are dead!  We
get more, and more accurate, information
from gcc via the readnone and readonly
function attributes.

from the old ADCE implementation (there it was
correct because the transform was being done
for read-only functions).

even though the bitcast operand did not have integer type.  This fixes
PR1814.

This makes the parser much easier to understand, eliminates a ton of global variables,
and gives tblgen nice caret diagnostics.  It is also faster, but tblgen probably doesn't
care about performance.

There are a couple of FIXMEs which I will take care of next.

Store output and input operands as well as clobber information in the AsmStmt. Ted, could you please review the serialization/deserialization code?

node A gets back into the DAG again because it was hiding in
one of the node maps: make sure that node replacement happens
in those maps too.

I added the lexing files to the VStudio projects and removed the .l files from the 
VStudio projects.  There was a problem with use of strtoll in TGLexer.cpp and Chris
suggested switching to strtol, so that's included here.

Additionally, this checkin adds minimal x64 builds to the VStudio builds.  Build issues
related to x64 in the windows specific files for DynamicLibrary.inc and Singals.inc
are worked around, but not ultimately solved.  Binaries used to be stored in

...\win32\{Debug|Release}

but are now kept in

...\win32\bin\{win32|x64}\{Debug|Release}

intermediate files will continue to be stored in the individual project directories under 
win32.  

Some names will likely change in the future to reflect that the vstudio projects
are no longer 32-bit only, but I wanted to get things up and running today so kept away
from bigger restructuring.
