    • runtime: persistentalloc and cache itabs · 1da37f43 
          
    Previously, each time we do an interface conversion for which the
    method table is not known at compile time, we allocate a new
    method table.
    
    This CL ports the mechanism of itab caching from the gc runtime,
    adapted to our itab representation and method finding mechanism.
    With the cache, we reuse the same itab for the same (interface,
    concrete) type pair. This reduces allocations in interface
    conversions.
    
    Unlike the gc runtime, we don't prepopulate the cache with
    statically allocated itabs, as currently we don't have a way to
    find them. This means we don't deduplicate run-time allocated
    itabs with compile-time allocated ones. But that is not too bad
    -- it is just a cache anyway.
    
    As now itabs are never freed, it is also possible to drop the
    write barrier for writing the first word of an interface header.
    I'll leave this optimization for the future.

    • PR libstdc++/61761 fix std::proj for targets without C99 cproj · 4f75543d 
      The current generic implementation of __complex_proj used when cproj is
not available calculates the wrong projection, giving a different result
than given by C99's cproj.

When C99 cproj is not available but isinf and copysign are, use those to
give correct results for float, double and long double. Otherwise, and
for other specializations of std::complex, just use a generic version
that returns its argument, and so doesn't support infinities.

We might want to consider adding additional overloads of __complex_proj
to support extended types such as _Float64x, _Float128 etc.

	PR libstdc++/61761
	* include/std/complex (__complex_proj): Return parameter unchanged.

	[_GLIBCXX_USE_C99_MATH_TR1] (__complex_proj): Add overloads for
	floating-point types.
