Fix portability bugs in valgrind support.
Update valgrind.h and memcheck.h to copies from valgrind-3.6.0.
This fixes portability to compilers other than gcc, notably
Solaris CC and HP-UX CC.
Fixes: bug #1050.

+/* This is all pretty complex. It's so as to make stack unwinding
+ work reliably. See bug 243270. The basic problem is the sub and
+ add of 128 of %rsp in all of the following macros. If gcc believes
+ the CFA is in %rsp, then unwinding may fail, because what's at the
+ CFA is not what gcc "expected" when it constructs the CFIs for the
+ places where the macros are instantiated.
+
+ But we can't just add a CFI annotation to increase the CFA offset
+ by 128, to match the sub of 128 from %rsp, because we don't know
+ whether gcc has chosen %rsp as the CFA at that point, or whether it
+ has chosen some other register (eg, %rbp). In the latter case,
+ adding a CFI annotation to change the CFA offset is simply wrong.
+
+ So the solution is to get hold of the CFA using
+ __builtin_dwarf_cfa(), put it in a known register, and add a
+ CFI annotation to say what the register is. We choose %rbp for
+ this (perhaps perversely), because:
+
+ (1) %rbp is already subject to unwinding. If a new register was
+ chosen then the unwinder would have to unwind it in all stack
+ traces, which is expensive, and
+
+ (2) %rbp is already subject to precise exception updates in the
+ JIT. If a new register was chosen, we'd have to have precise
+ exceptions for it too, which reduces performance of the
+ generated code.
+
+ However .. one extra complication. We can't just whack the result
+ of __builtin_dwarf_cfa() into %rbp and then add %rbp to the
+ list of trashed registers at the end of the inline assembly
+ fragments; gcc won't allow %rbp to appear in that list. Hence
+ instead we need to stash %rbp in %r15 for the duration of the asm,
+ and say that %r15 is trashed instead. gcc seems happy to go with
+ that.
+
+ Oh .. and this all needs to be conditionalised so that it is
+ unchanged from before this commit, when compiled with older gccs
+ that don't support __builtin_dwarf_cfa. Furthermore, since
+ this header file is freestanding, it has to be independent of
+ config.h, and so the following conditionalisation cannot depend on
+ configure time checks.
+
+ Although it's not clear from
+ 'defined(__GNUC__) && defined(__GCC_HAVE_DWARF2_CFI_ASM)',
+ this expression excludes Darwin.
+ .cfi directives in Darwin assembly appear to be completely
+ different and I haven't investigated how they work.
+
+ For even more entertainment value, note we have to use the
+ completely undocumented __builtin_dwarf_cfa(), which appears to
+ really compute the CFA, whereas __builtin_frame_address(0) claims
+ to but actually doesn't. See
+ https://bugs.kde.org/show_bug.cgi?id=243270#c47
