This patch adds a class that provides basic hash/equal functions
for vectors, based on corresponding traits for the element type.

int_hash combines two kinds of operation:
(1) hashing and equality of integers
(2) using spare integer encodings to represent empty and deleted slots
(1) is really independent of (2), and could be useful in cases where
no spare integer encodings are available. This patch adds a base class
(int_hash_base) for (1) and makes int_hash inherit from it.
If we follow a similar style for future hashes, we can make
unbounded_hashmap_traits take the "base" hash for the key
as a template parameter, rather than requiring every type of
key to have a separate derivative of unbounded_hashmap_traits.
A later patch applies this to vector keys.
No functional change intended.
gcc/
* hash-traits.h (int_hash_base): New struct, split out from...
(int_hash): ...this class, which now inherits from int_hash_base.
* hash-map-traits.h (unbounded_hashmap_traits): Take a template
parameter for the key that provides hash and equality functions.
(unbounded_int_hashmap_traits): Turn into a type alias of
unbounded_hashmap_traits.

Before the patch, compiling the hello world example of libgccjit with
the external driver under Valgrind shows a loss of 12,611 (48 direct)
bytes. After the patch, no memory leaks are reported anymore.
(Memory leaks occurring when using the internal driver are mostly in
the driver code in gcc/gcc.c and have to be fixed separately.)
The patch has been tested by fully bootstrapping the compiler with the
frontends C, C++, Fortran, LTO, ObjC, JIT and running the test suite
under a x86_64-pc-linux-gnu host.

The following patch adds support for relocation of the PCH blob on PCH
restore if we don't manage to get the preferred map slot for it.
The GTY stuff knows where all the pointers are, after all it relocates
it once during PCH save from the addresses where it was initially allocated
to addresses in the preferred map slot.
But, if we were to do it solely using GTY info upon PCH restore, we'd need
another set of GTY functions, which I think would make it less maintainable
and I think it would also be more costly at PCH restore time. Those
functions would need to call something to add bias to pointers that haven't
been marked yet and make sure not to add bias to any pointer twice.
So, this patch instead builds a relocation table (sorted list of addresses
in the blob which needs relocation) at PCH save time, stores it in a very
compact form into the gch file and upon restore, adjusts pointers in GTY
roots (that is right away in the root structures) and the addresses in the
relocation table.
The cost on stdc++.gch/O2g.gch (previously 85MB large) is about 3% file size
growth, there are 2.5 million pointers that need relocation in the gch blob
and the relocation table uses uleb128 for address deltas and needs ~1.01 bytes
for one address that needs relocation, and about 20% compile time during
PCH save (I think it is mainly because of the need to qsort those 2.5
million pointers). On PCH restore, if it doesn't need relocation (the usual
case), it is just an extra fread of sizeof (size_t) data and fseek
(in my tests real time on vanilla tree for #include <bits/stdc++.h> CU
was ~0.175s and with the patch but no relocation ~0.173s), while if it needs
relocation it took ~0.193s, i.e. 11.5% slower.
Without PCH that
#include <bits/stdc++.h>
int i;
testcase compiles with -O2 -g in ~1.199s, i.e. 6.2 times slower than PCH with
relocation and 6.9 times than PCH without relocation.
The discovery of the pointers in the blob that need relocation is done
in the relocate_ptrs hook which does the pointer relocation during PCH save.
Unfortunately, I had to make one change to the gengtype stuff due to the
nested_ptr feature of GTY, which some libcpp headers and stringpool.c use.
The relocate_ptrs hook had 2 arguments, pointer to the pointer and a cookie.
When relocate_ptrs is done, in most cases it is called solely on the
subfields of the current object, so e.g.
if ((void *)(x) == this_obj)
op (&((*x).u.fld[0].rt_rtx), cookie);
so relocate_ptrs can assert that ptr_p is within the
state->ptrs[state->ptrs_i]->obj ..
state->ptrs[state->ptrs_i]->obj+state->ptrs[state->ptrs_i]->size-sizeof(void*)
range and compute from that the address in the blob which will need
relocation (state->ptrs[state->ptrs_i]->new_addr is the new address
given to it and ptr_p-state->ptrs[state->ptrs_i]->obj is the relative
offset. Unfortunately, for nested_ptr gengtype emits something like:
{
union tree_node * x0 =
((*x).val.node.node) ? HT_IDENT_TO_GCC_IDENT (HT_NODE (((*x).val.node.node))) : NULL;
if ((void *)(x) == this_obj)
op (&(x0), cookie);
(*x).val.node.node = (x0) ? CPP_HASHNODE (GCC_IDENT_TO_HT_IDENT ((x0))) : NULL;
}
so relocate_ptrs is called with an address of some temporary variable and
so doesn't know where the pointer will finally be.
So, I've added another argument to relocate_ptrs (and to
gt_pointer_operator). For the most common case I pass NULL as the new middle
argument to that function, first one remains pointer to the pointer that
needs adjustment and last the cookie. The NULL seems to be cheap to compute
and short in the gt*.[ch] files and stands for ptr_p is an address within
the this_obj's range, remember its address. For the nested_ptr case, the
new middle argument contains actual address of the pointer that might need
to be relocated, so instead of the above
op (&(x0), &((*x).val.node.node), cookie);
in there. And finally, e.g. for the reorder case I need a way to tell
restore_ptrs to ignore a particular address for the relocation purposes
and only treat it the old way. I've used for that the case when
the first and second arguments are equal.
In order to enable support for mapping PCH as fallback at different
addresses than the preferred ones, a small change is needed to the
host pch_use_address hooks. One change I've done to all of them is
the change of the type of the first argument from void * to void *&,
such that the actual address can be told to the callers (or shall I
instead use void **?), but another change that still needs to be done
in them if they want the relocation is actually not fail if they couldn't
get a preferred address, but instead modify what the first argument
refers to. I've done that only for host-linux.c and Iain is testing
similar change for host-darwin.c. Didn't change hpux, netbsd, openbsd,
solaris, mingw32 or the fallbacks because I can't test those.
Tested also with the:

hack which forces all PCH restores to be relocated. An earlier version of the
patch has been also regrest with base = (char *) base + 16384; in that spot,
so both relocation to a non-overlapping spot and to an overlapping spot have
been tested.
