aeb5c7b353 Implement "visitPow". This is mainly used to see if we have a pow() call of this
form:

          powf(10.0f, x);

If this is the case, and also we want limited precision floating-point
calculations, then lower to do the limited-precision stuff.

4344a5d0d7 Change -fast-isel-no-abort to -fast-isel-abort, which now defaults
to being off by default. Also, add assertion checks to check that
the various fast-isel-related command-line options are only used
when -fast-isel itself is enabled.

d2e51af035 Move the uglier parts of deciding not to emit a
UsedDirective for some symbols in llvm.used into
Darwin-specific code.  I've decided LessPrivateGlobal
is potentially a useful abstraction and left it in
the target-independent area, with improved comment.

99c1a7c9e1 Correct callgraph construction. It has two problems:
(1) code left over from the days of ConstantPointerRef:
if a use of a function is a GlobalValue then that is
not considered a reason to add an edge from the external
node, even though the use may be as an initializer for
an externally visible global!  There might be some point
to this behaviour when the use is by an alias (though the
code predated aliases by some centuries), but I think
PR2782 is a better way of handling that.  (2) If function
F calls function G, and also G is a parameter to the
call, then an F->G edge is not added to the callgraph.
While this doesn't seem to matter much, adding such an
edge makes the callgraph more regular.
In addition, the new code should be faster as well as
simpler.

the magic 'l' prefix for symbols on Darwin which are
to be passed through the assembler, then removed at
linktime (previously all references to this had been
hidden in the ObjC FE code, oh well).

f72fb679ef Extend the vcmp/fcmp LLVM IR instructions to take vectors as arguments
and, if so, to return a vector of boolean as a result;

Extend the select LLVM IR instruction to allow you to specify a result
type which is a vector of boolean, in which case the result will be an
element-wise selection instead of choosing one vector or the other; and

Update LangRef.html to describe these changes.
