85bf8a0497 interpreter: Implement correct rounding for fmadds/ps_madd. 
Simply casting a double-precision result to single-precision can result
in an incorrect LSB if the double-precision result is inexact but the
rounded value is exactly between two single-precision values.

84a63ef51e interpreter: Use the proper floating-point type when setting FPRF. 
This makes a difference when the result to a single-precision
instruction is a single-precision denormal; passing it as a double
causes FPRF to signal a normal result instead of a denormal.

628fea9074 interpreter: Properly detect underflow of floating-point operations. 
PowerPC CPUs detect underflow using different conditions than x86 CPUs,
so if we get a rounded result equal to the minimum normal value, we
need to manually check for underflow.  See comments in fpArithGeneric()
for details.

8c34c9e845 espresso: Ignore register fields which are ignored by hardware. 
A real Espresso ignores some register fields which are unused by certain
instructions, such as frC in fadd.  Such invalid opcodes are presumably
not generated by any real-life compilers, but ignore such fields anyway
for completeness.  This may also provide a marginal performance boost to
the interpreter.

This is probably not a complete set of ignored fields, but it's enough
to pass all relevant tests in the current test suite at
<http://achurch.org/cpu-tests/ppc750cl.s>.

19d8091287 gpu: Optimize copying between linear-mode surfaces. 
The single function AddrComputeSurfaceAddrFromCoord<1, false, 8, 0> was
consuming 20% of CPU time (over all threads!) during the Xenoblade intro
movie.

848014a538 opengl: Use a sorted resource map to optimize resource updates. 
Since resources are not currently expunged when the memory is reused for
another purpose, the resource maps grow over time, causing the linear
scans in notify{Cpu,Gpu}Flush() and surfaceSync() to consume more and
more CPU as time goes on.  This change introduces a ResourceMemoryMap
class to keep a sorted list of resource memory endpoints, so the scans
can touch exactly those resources that fit the requested memory range
without having to iterate over every single allocated resource.

4f6c55e6ab Seperate gfd::File into gfd::Reader and gfd::Writer.

the 32 bit pointers in order to fixup the GX2 structs.

d871756e66 Fix some things that were missed in the last commit. 
There were some crazy changes to the debugger::ui drawing
code that I hadn't noticed.  I fixed them and then added
the blank DX12 drawer as I did with the rest of the draw
components.
