After speaking briefly with Chris, we decided this should be a front-end fix.
The fix...have Sema::GetTypeForDeclarator() do the default function/array conversion, as
I outlined in the 9/9 email on this topic.
Since this conversion is done before Sema::ParseParamDeclarator(), I thought I could
remove the conversion from Sema::ParseParamDeclarator(). Unfortunately, this didn't work.
The conversion apparently needs to be done in both places (which doesn't make sense to me).
Will investigate.

2. Lower calls to fabs and friends to FABS nodes etc unless the function has
internal linkage. Before we wouldn't lower if it had a definition, which
is incorrect. This allows us to compile:
define double @fabs(double %f) {
%tmp2 = tail call double @fabs( double %f )
ret double %tmp2
}
into:
_fabs:
fabs f1, f1

instruction. These are implemented with xor which will modify the conditional
code. They should be rematerialized as move instructions.

that refer to direct function calls.
Modified interface of LiveVariables to only track liveness of VarDecls.
This cleans up a bunch of edge cases, and removed the bug just mentioned.

"CFGVisitor", which now handles all the boilerplate for iterating over
the function definitions in a translation unit and building the CFGs.
This logic was previously replicated for each driver option that used
CFGs.
The options -dump-cfg, -view-cfg, -check-dead-stores, and
-dump-live-variables now use this refactored code.

but never used.
Fix a bug in LiveVariables where uses on the LHS of self-assign
operators (e.g +=, *=, etc) would not be properly recorded in the
liveness state of the variable.

to variables that are no longer live. This analysis is built on top
of CFGs and the LiveVariables analysis.
changes to driver:
added driver option "-check-dead-stores" to run the analysis

as types. That said, the AST nodes ObjcInterfaceDecl, ObjcInterfaceType, and ObjcClassDecl are *very*
preliminary.
The good news is we no longer need -parse-noop (aka MinimalActions) to parse cocoa.m.

Use APFloat in UpgradeParser and AsmParser.
Change all references to ConstantFP to use the
APFloat interface rather than double. Remove
the ConstantFP double interfaces.
Use APFloat functions for constant folding arithmetic
and comparisons.
(There are still way too many places APFloat is
just a wrapper around host float/double, but we're
getting there.)
