  [demangler] PPC and S390: Fix parsing of e-prefixed long double literals

Summary:
This patch is to fix the parsing of long double literals encoded with the e prefix on PowerPC and S390. For both PowerPC and S390, type code e is used for 64-bit long double literals and g is used for 128-bit long double literals. libcxxabi test case test_demangle.pass.cpp fails without the fix.
