As pointed out by Michel Dänzer, gcc -lstdc++ doesn't work on all systems,
because it may require other libraries which are only pulled in implicitly
by g++. And libstdc++ is available only with GNU compiler.
Use c++ compiler for linking and remove redundant LDFLAGS += -lstdc++
all over the tree.
Scalar instruction that need to write to the xyz components of a
register must reserve the RGB instruction slot for a REPL_ALPHA
instruction. With this commit, the scheduler will attempt to free
the RGB slot by moving the write to the w component of a register.
This is required for an accurate implementation of d3d1x's
CheckFormatSupport query.
It also seems generally useful for state trackers, which could
choose alternative rendering paths or formats if blending would
come at a significant performance loss.
The texture semaphore allows for prefetching of texture data. On my
RV515, this increases the FPS of Lightsmark by 33% (This is with the
reg_rename pass enabled, which is enabled in the next commit).
There is a new env variable now called RADEON_TEX_GROUP, which allows
you to specify the maximum number of texture lookups to do at once.
The default is 8, but different values could produce better results
for various application / card combinations.
We no longer emit full instructions immediately after they have been
merged. Instead merged instructions are added to the ready list and
the scheduler can commit them whenever it wants.
Don't allow any "CPU" buffers to be allocated by the pb_fenced
buffer manager, since we can't protect against failures during
buffer validation.
Also, add an extra slab buffer manager to allocate buffers from
the kernel if there is a failure to allocate from our big buffer pool.
The reason we use a slab manager for this, is to avoid allocating
many very small buffers from the kernel.
v2: Increased VMW_MAX_BUFFER_SIZE and fixed some comments.

But don't hook it up just yet until we figure out a good way to do that.
Also, we should, in the future, add driconf options to control what
throttling reasons should be honored, and the number of outstanding
swaps allowed.

This change releases the stw_framebuffer::mutex past creation of
the pbuffer stw_framebuffer. Without this change the pbuffers
lock is never released. Since on win32 mutexes are recursive, this
does not hurt as long as all actions on a context are done from
the same thread. But if, for example, context creation happens in
a different thread than usage, every access to the context will
block for ever.

Previously it was getting set in draw_set_mapped_constant_buffer() but
if there were no shader constants, that function wasn't called. So the
pt.user.planes field was null and we died when we tried to access the
clip planes in the LLVM-generated code.
Fixes https://bugs.freedesktop.org/show_bug.cgi?id=41663
Note: This is a candidate for the 7.11 branch.

Instead of 12 use DRAW_TOTAL_CLIP_PLANES. The max number of user-defined
clip planes was increased to 8 so the total number of planes is 14.
This doesn't fix any specific bug, but clearly the old code was wrong.

now that we have integer texture types I can drop this workaround so that
copies of values is done properly (as floats would fail on some corner cases).
