This change does a couple of things. First it gets the Visual Studio builds working.
...
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.

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.

Reverted patch 44199:
...
http://llvm.org/viewvc/llvm-project?rev=44199&view=rev
This patch completely broke serialization due to an invariant I assumed but
did not hold. The assumed invariant was that all pointer IDs emitted by a call
to BatchEmitOwnedPtrs would be consecutive. This is only the case if there has
been no forward references to an owned pointer (and hence already registered
with the Serializer object).

Implemented optimization for BatchEmitOwnedPtrs that we only emit one complete
...
SerializedPtrID, followed by the *differences* in IDs. The big idea is that
most IDs will be just be 1 off from the previous (either that or NULL, which
we encode as a difference if 0), so this will greatly reduce the encoding
space for extra IDs to just 1 bit per pointer.
So far this optimization reduces serialization of Carbon.h by only 1%, but
we aren't using any abbreviations now in the Bitcode file to properly take
advantage of this optimization.

Live interval splitting:
...
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.

Unify CALLSEQ_{START,END}. They take 4 parameters: the chain, two stack
...
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).
This can only result in tears...

Added versions of ReadPtr that takes an explicit SerializedPtrID. This allows
...
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.
