Log:
add some final random notes, I've completed my pass over all the commits.
I'll work on turning this into something intelligible tomorrow.

X86: inline assembler supports .code32 and .code64.
Exception handling rewrite: new landingpad and resume instruction. Unwind gone.
LowerSetJmp pass removed, unused.

Old arm disassembler replaced with a new one based on autogenerated encoding information from ARM .td files.
Frontend tests removed from llvm/test/Frontend* (was this completed for 3.0?)
Segmented stack support (X86 only?) Rafael and Sanjoy Das: docs/SegmentedStacks.html should be in CodeGen.html status table?

Codegen now supports vector "select" operations on vector comparisons, turning
them into various optimized code sequences (e.g. using the SSE4/AVX "blend"
instructions).

+ #line directives in integrated assembler
+ SSE domain fixing code enabled for AVX (Bruno/Jakob). Domain fixing pass is
+ now target independent (ExecutionDepsFix pass). (Jakob)
+ X86 backend synthesizes horizontal add/sub instructions from generic code.
+ returns_twice attribute (rafael)
+ Tablegen has been split into a library, clang tblgen pieces now live in clang.
+ The llvm version is now named llvm-tblgen instead of tblgen.
+ X86: Tons of encoding improvements and new instructions (e.g. Atom, Ivy Bridge,
+ and BMI instructions)
+ added to assembler and disassembler (Craig Topper)
+ data layout string can encode the natural alignment of the target's stack for better optimization (LangRef.html#datalayout)
