<pre>The following literals trick NumericLiteralParser into believing that they have
an exponent or significand when they don't. Later when GetFloatValue tries to
process them the empty exponent or significand is detected and triggers an
assertion.
They also diagnose the digit separator as being both at the start and end of a
digit sequence.
float f = 0x.'p1f;
float g = 0e'f;
This one doesn't trigger an assertion, but isn't diagnosed as an empty exponent
either.
float h = 0x0p'f;</pre>
