Nick Lewycky 3783b46f9e Instead of calculating constant factors, calculate the number of trailing
bits. Patch from Wojciech Matyjewicz.

Duncan Sands b87dde7e8e Fix a bug in which node A is replaced by node B, but later
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.

Chuck Rose III 07b57d2626 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.

Duncan Sands 04eb67e69a In order for parameter attribute uniquing to make
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.

Chris Lattner 09c0393d5e ExpandUnalignedLoad doesn't handle vectors right at all apparently.
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.

Evan Cheng 8e22379303 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.

Evan Cheng 7f02cfa599 Clean up sub-register implementation by moving subReg information back to
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.
