Fix hex floating point lexing
PR gdb/18318 notes that gdb will sometimes incorrectly handle hex
floating point input. This turns out to be a bug in the C lexer; the
'p' was not being correctly recognized, and so the exponent was not
always passed to the floating point "from_string" method.
Tested by the buildbot "Fedora-x86_64-m64" builder.
