Converting a _Complex type to a real one simply discards the imaginary part. This can easily lead to loss of information so for safety (and GCC compatibility) this patch disallows that when the conversion would be implicit. The one exception is bool, which actually compares both real and imaginary parts and so is safe. llvm-svn: 310427
