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

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.

any sense it is important that ParamAttr::None gets
treated the same as not supplying an attribute at
all. Rather than stripping ParamAttr::None out of
the list of attributes, assert if ParamAttr::None
is seen. Fix up the bitcode reader which liked to
insert ParamAttr::None all over the place. Patch
based on one by Török Edwin.

Fix a couple of problems:
1. Don't assume the VT-1 is a VT that is half the size.
2. Treat vectors of FP in the vector path, not the FP path.
This has a couple of remaining problems before it will work with
the code in PR1811: the code below this change assumes that it can
use extload/shift/or to construct the result, which isn't right for
vectors.
This also doesn't handle vectors of 1 or vectors that aren't pow-2.

When a live interval is being spilled, rather than creating short, non-spillable
intervals for every def / use, split the interval at BB boundaries. That is, for
every BB where the live interval is defined or used, create a new interval that
covers all the defs and uses in the BB.
This is designed to eliminate one common problem: multiple reloads of the same
value in a single basic block. Note, it does *not* decrease the number of spills
since no copies are inserted so the split intervals are *connected* through
spill and reloads (or rematerialization). The newly created intervals can be
spilled again, in that case, since it does not span multiple basic blocks, it's
spilled in the usual manner. However, it can reuse the same stack slot as the
previously split interval.
This is currently controlled by -split-intervals-at-bb.

in favour of teaching CCAssignToStack that size 0 and/or align
0 means to use the ABI values. This seems a neater solution.
It is safe since no legal value type has size 0.

MachineOperand auxInfo. Previous clunky implementation uses an external map
to track sub-register uses. That works because register allocator uses
a new virtual register for each spilled use. With interval splitting (coming
soon), we may have multiple uses of the same register some of which are
of using different sub-registers from others. It's too fragile to constantly
update the information.

adjustment fields, and an optional flag. If there is a "dynamic_stackalloc" in
the code, make sure that it's bracketed by CALLSEQ_START and CALLSEQ_END. If
not, then there is the potential for the stack to be changed while the stack's
being used by another instruction (like a call).

clients of the Deserializer to read the pointer ID before they are ready
to deserialize the object (which can mean registering a pointer reference
with the backpatcher).
Changed some methods that took an argument "SerializedPtrID" to "const SerializedPtrID&" (pass-by-reference). This is to accommodate a future
revision of SerializedPtrID where it may be much fatter than an unsigned
integer.
