nir/spirv: Allow loop breaks in a switch body.

Per the SPIR-V spec 2.11 Structured Control Flow:

"The only blocks in a construct that can branch outside the construct are

...
- a break block for the innermost loop it is inside of.
..."

With

"Break block: A block containing a branch to the Merge Block of a loop header's merge instruction."

Note that it puts no restriction on not being in an if or switch within the innermost loop.

This passes the loop_break block to the switch body so it can properly detect loop breaks.

wayland-egl: rework and simplify wl_egl_window initialization

Use calloc instead of malloc + explicitly zeroing the different fields.
We need special handling for the version field which is of type
const intptr_t.

As we're here document why keeping the constness is a good idea.

width/height.

swr/rast: do not crash on NULL strings returned by getenv

The current convenience function GetEnv feeds the results of getenv
directly into std::string(). That is a bad idea, since the variable
may be unset, thus we feed NULL into the C++ construct.

freedreno/a5xx: align height to GMEM

Similar to the way width/pitch alignment works, it seems like we need to
do similar for height.  Otherwise the BLIT from system memory to GMEM
can over-fetch beyond the end of the buffer, triggering a fault.

I'm not sure if there is a better solution yet.  Possibly we could fall
back to pre-a5xx style DRAW packets for cases where BLIT might over-
fetch.  (We in theory have that problem already with rendering to higher
mipmap levels, although fortunately those tend to use GMEM bypass.)

This fixes issues reported with glamor.
