Revert most of the functionality in r165001. Instead, make sure that
the ASTReader doesn't attach a body to a function that is already
defined elsewhere.

Remove ASTReader::needPendingInstantiation(), introduced in r164993,
which is neither correct nor necessary. The use of this routine was
eliminated by r165137.

This patch enables general varargs support for the 64-bit PPC SVR4 ABI.

Most of the pieces for this were already in place, but a proper EmitVAArg
is needed for aggregates and complex numbers to be handled.  Although the
va_list for 64-bit PowerPC SVR4 consists of GPRs 3 through 10 together with
the overflow portion of the parameter save area, we can treat va_list as
pointing to contiguous memory for all parameters, since the back end forces
the parameter GPRs to memory for varargs functions.

There is no need at this time to model parameters and return values beyond
what the DefaultABIInfo provides.

Remove useless parameter "WantFile" from Driver::GetProgramPath().
This parameter is useless because nowhere used explicitly and always
gets its default value - "false".

Always initialize FPContractable.

false is used as a baseline here, we may want to allow contraction in some of
the cases.  Found by valgrind.

Fix invalid reads by memcmp.

Str may be smaller than Start->Name here. Use strncmp to avoid scanning past the
