This just provides a way to look up a LibFunc::Func enum value for a
function name.  Alphabetize the enums and function names so we can use a
binary search.

make all Emit*() functions consult the TargetLibraryInfo information before creating a call to a library function.
Update all clients to pass the TLI information around.

Enhance both TargetLibraryInfo and SelectionDAGBuilder so that the latter can use the former to prevent the formation of libm SDNode's when  -fno-builtin is passed.

Add support for custom names for library functions in TargetLibraryInfo.  Add a custom name for fwrite and fputs on x86-32 OSX.  Make SimplifyLibCalls honor the custom
names for fwrite and fputs.
