Reduce memory usage for storing LTO decl resolutions

With a LTO build of a large project (>11k subfiles incrementially linked)
storing the LTO resolutions took over 0.5GB memory:

lto/lto.c:1087 (lto_resolution_read)                      0: 0.0%  540398500           15903: 0.0%

The reason is that the declaration indexes are quite sparse, but every subfile
got a full continuous vector for them. Since there are so many of them the
many vectors add up.

This patch instead stores the resolutions initially in a compact (index, resolution)
format. This is only expanded into a sparse vector for fast lookup when
the subfile is actually read, but then immediately freed. This means only one
vector is allocated at a time.

This brings the overhead for this down to less than 3MB for the test case:

lto/lto.c:1087 (lto_resolution_read)                      0: 0.0%    2821456           42186: 0.0%

Fix bootstrap failure with clang++.

This patch fixes a bootstrap failure when using clang as the host
compiler.  Default arguments for class template member functions

This patch works around a parsing problem with g++ 4.3.  The parser is
failing to lookup calls to the template function reserve when called
from other member functions:

vec_t<T>::reserve<A> (...)

The parser thinks that the '<' in reserve<A> is a less-than operation.
This problem does not happen after 4.3.

This code is going to change significantly, so this won't be needed
soon.

Make all VEC_* functions, member functions of vec_t.

This patch is the first step towards making the API for VEC use
member functions.

There are no user code modifications in this patch.  Everything
is still using the VEC_* macros, but this time they expand into
member function calls.

Because of the way VECs are used, this required some trickery.
The API allows VECs to be NULL.  This means that services like
VEC_length(V) will return 0 when V is a NULL pointer.  This is,
of course, not possible to do if we call V->length().

For functions that either need to allocate/re-allocate the
vector, or they need to handle NULL vectors, I implemented them
as static member functions or free functions.

Another wart that I did not address in this patch is the fact
that vectors of pointers and vectors of objects have slightly
different semantics when handling elements in the vector.  In
vector of pointers, we pass them around by value, but in vectors
of objects, they are passed around via pointers.  That's why we
need TYPE * and TYPE ** overloads for some functions (e.g.,
vec_t::iterate).

I will fix these two warts in a subsequent patch.  The idea is to
make vec_t a single-word structure, which acts as a handler for
the structure containing the actual vector.  Something like this:

template<typename T>
struct vec_t
{
  struct vec_internal<T> *vec_;
};

This has the advantage that we can now declare the actual vector
instances as regular variables, instead of pointers.  They will
use the same amount of memory when embedded in other structures,
and we will be able to allocate and reallocate the actual data
without having to mutate the vector instance.

All the functions that are now static members in vec_t, will
become instance members in the new vec_t.  This will mean that
all the callers will need to be changed, of course.

Tested on x86_64 and ppc64 with all languages plus ada, go and obj-c++.

Rewrite VEC_* functions as member functions of vec_t.
