e25ca692c0 Implement simple support for vector casting. This can currently only handle 
casts between legal vector types.

f2722ca339 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.

63d3300da1 - 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.

ecfe55e65b 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).

7d6a5155a4 Cause the various warnings list to be generated via a <ul> list with 
text enclosed in <tt>. This ensures that (a) the text is in a fixed width
font (to indicated generated text) and (b) the text wraps without causing
the page width to be extended. The main result of this is that the report
will wrap to conform to the window size in which it is displayed instead of
having a very wide length if a warning message is long.
