Bug ID: 40779
Summary: clang trunk thinks 1+1 is 9223372036854775810
(converting `long double` to `size_t`)

testcase
STR:
1. Compile and run the attached testcase program, the key part of which is
here:
> long double one = 1;
> size_t result(one + 1); // This should equal 2.
ACTUAL RESULTS, with locally-built clang version 9.0.0 (trunk 354359):
The program prints:
> Failed (expected 2 and got 9223372036854775810)
EXPECTED RESULTS:
The program should print:
> Success (expected 2 and got 2)
This is causing a startup crash in my locally-built Firefox, compiled with
locally-built Clang (from llvm trunk 354359).
