078f455d15 Implement correctly-rounded decimal->binary conversion, i.e. conversion 
from user input strings.

Such conversions are more intricate and subtle than they may appear;
it is unlikely I have got it completely right first time.  I would
appreciate being informed of any bugs and incorrect roundings you
might discover.

a75e4a62e6 Change the names used for internal labels to use the current 
function symbol name instead of a codegen-assigned function
number.

Thanks Evan! :-)

d11cd4a095 EXTRACT_SUBREG coalescing support. The coalescer now treats EXTRACT_SUBREG like 
(almost) a register copy. However, it always coalesced to the register of the
RHS (the super-register). All uses of the result of a EXTRACT_SUBREG are sub-
register uses which adds subtle complications to load folding, spiller rewrite,
etc.

e47ae5fe94 make operator== work with non-equal sized bitvectors, as long as 
the extra bits are all zeros.  This allows  "010" and "010000" to be
treated as equal.

ab5c3ed0d1 Add intrinsics for sin, cos, and pow. These use llvm_anyfloat_ty, and so 
may be overloaded with vector types. And add a testcase for codegen for
these.

d47210011e Added tail call optimization to the x86 back end. It can be 
enabled by passing -tailcallopt to llc.  The optimization is
performed if the following conditions are satisfied:
* caller/callee are fastcc
* elf/pic is disabled OR
  elf/pic enabled + callee is in module + callee has
  visibility protected or hidden

0ee2a2fb59 Next PPC long double bits. First cut at constants. 
No compile-time support for constant operations yet,
just format transformations.  Make readers and
writers work.  Split constants into 2 doubles in
Legalize.

a8e090bd1c Added implementation of immutable (functional) maps and sets, as 
implemented on top of a functional AVL tree.  The AVL balancing code
is inspired by the OCaml implementation of Map, which also uses a functional
AVL tree.

Documentation is currently limited and cleanups are planned, but this code
compiles and has been tested.

f003f9bf1a Add a new function tcExtract for extracting a bignum from an 
arbitrary range of bits embedded in the middle of another bignum.
This kind of operation is desirable in many cases of software
floating point, e.g. converting bignum integers to floating point
numbers of fixed precision (you want to extract the precision most
significant bits).

Elsewhere, add an assertion, and exit the shift functions early if
the shift count is zero.

db4dbedfea Reimplement convertFromUnsignedInteger so it is passed a const bignum. 
It used to modify its argument in-place.

This interface is saner and the implementation more efficient.  It will
be needed for decimal->binary conversion.

6e01c5df37 convertFromInteger, as originally written, expected sign-extended 
input.  APInt unfortunately zero-extends signed integers, so Dale
modified the function to expect zero-extended input.  Make this
assumption explicit in the function name.
