71367ee945 A very early, rough draft of a guide to making public releases for LLVM. 
This document will detail the steps needed for making a quality release of
LLVM that ensures the release functions and is of high quality.

b2fb37b983 Updated for library changes: 
1. LLVMCBackend.o now depends on LLVMCodeGen.o (why we're not sure)
2. LLVMExecutionEngine.o no longer depends on LLVMInterpreter.o nor LLVMJIT.o
Thanks, Chris.

Make the CBE and V9 backends create their own, since they're the only ones that use it.

5b747af8e1 These changes are necessary to support the new llvm-config tool. llvm-config 
is a handy tool for users of LLVM who want to be able to quickly get
information about LLVM's configuration. It is intended to be used in the
command line of other tools. Documentation will be forthcoming in a
subsequent patch.

f6dc0a7f5e - VECTOR_SHUFFLE of v4i32 / v4f32 with undef second vector always matches 
PSHUFD. We can make permutes entries which point to the undef pointing
  anything we want.
- Change some names to appease Chris.

ab22cd5c33 Eliminate the dependency of ExecutionEngine on the JIT/Interpreter libraries.

f84f3bf95b When possible, custom lower 32-bit SINT_TO_FP to this: 
_foo2:
        extsw r2, r3
        std r2, -8(r1)
        lfd f0, -8(r1)
        fcfid f0, f0
        frsp f1, f0
        blr

instead of this:

_foo2:
        lis r2, ha16(LCPI2_0)
        lis r4, 17200
        xoris r3, r3, 32768
        stw r3, -4(r1)
        stw r4, -8(r1)
        lfs f0, lo16(LCPI2_0)(r2)
        lfd f1, -8(r1)
        fsub f0, f1, f0
        frsp f1, f0
        blr

This speeds up Misc/pi from 2.44s->2.09s with LLC and from 3.01->2.18s
with llcbeta (16.7% and 38.1% respectively).
