David Greene 5d0c051e66 Operation Enhancements
Create an OpInit class to serve as a base for all operation Inits.

Move parsing of operation constructs to separate functions and reference
from multiple places.

Add some commented out new operations.  Coming soon.

David Greene 44f9d7a8f0 Allow multiclass def names to contain "#NAME"" where TableGen replaces
#NAME# with the name of the defm instantiating the multiclass.  This is
useful for AVX instruction naming where a "V" prefix is standard
throughout the ISA.  For example:

multiclass SSE_AVX_Inst<...> {
   def SS : Instr<...>;
   def SD : Instr<...>;
   def PS : Instr<...>;
   def PD : Instr<...>;

   def V#NAME#SS : Instr<...>;
   def V#NAME#SD : Instr<...>;
   def V#NAME#PS : Instr<...>;
   def V#NAME#PD : Instr<...>;
}

defm ADD : SSE_AVX_Inst<...>;

Results in 

ADDSS
ADDSD
ADDPS
ADDPD

VADDSS
VADDSD
VADDPS
VADDPD

David Greene a9c6c5d39b Implement !nameconcat to concatenate strings and look up the resulting
name in the symbol table, returning an object.

Chris Lattner 8bd06d8e1b Fix escaping in asm string literals correctly by having tblgen unescape
them, then the asmprinter emitter reescape them.

Dan Gohman ca0546facc Fun x86 encoding tricks: when adding an immediate value of 128,
use a SUB instruction instead of an ADD, because -128 can be
encoded in an 8-bit signed immediate field, while +128 can't be.
This avoids the need for a 32-bit immediate field in this case.

A similar optimization applies to 64-bit adds with 0x80000000,
with the 32-bit signed immediate field.

To support this, teach tablegen how to handle 64-bit constants.

Chris Lattner 6f2ffdb73f Change the MemoryBuffer::getFile* methods to take just a pointer to the
start of a filename, not a filename+length.  All clients can produce a
null terminated name, and the system api's require null terminated 
strings anyway.

Chris Lattner f4127dd48e Rewrite the tblgen parser in a recursive descent style, eliminating the bison parser.
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.

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.

Chris Lattner da4ab67127 reimplement the tblgen lexer with a simple hand-written lexer. This eliminates
one dependency on flex and gets rid of two ".cvs" files.
