Use head/tail ring buffer indices for thread synchronization.
1. SwrWaitForIdle loops until ring is empty. (head == tail)
2. GetDrawContext waits until ring is not full. (head - tail) == Ring Size
3. Draw enqueues by incrementing head.
4. Last worker thread to move past a DC dequeues by incrementing tail.
Todo: To reduce contention we can cache the tail in the API thread. For
example, if you know you have 64 free entries in the ring then you don't
need to keep checking the tail until you used those 64 entries.
The programming of the L3 Cache registers should match the previous
manually packed LRI values.

From the ES 3.2 spec, section 16.1.1 (Selecting Buffers for Reading):
"An INVALID_ENUM error is generated if src is not BACK or one of
the values from table 15.5."
Table 15.5 contains NONE and COLOR_ATTACHMENTi.
Mesa properly returned INVALID_ENUM for unknown enums, but it decided
what was known by using read_buffer_enum_to_index, which handles all
enums in every API. So enums that were valid in GL were making it
past the "valid enum" check. Such targets would then be classified
as unsupported, and we'd raise INVALID_OPERATION, but that's technically
the wrong error code.

This commit adds a NIR pass for lowering away returns in functions. If the
return is in a loop, it is lowered to a break. If it is not in a loop,
it's lowered away by moving/deleting code as needed.

The efficiency should be approximately the same. We do a little more work
per phi node because we have to sort the predecessors. However, we no
longer have to walk the blocks a second time to pop things off the stack.
The bigger advantage, however, is that we can now re-use the phi placement
and per-block SSA value tracking in other passes.
As a side-benifit, the phi builder actually handles unreachable blocks
correctly. The original vars_to_ssa code, because of the way it iterated
the blocks and added phi sources, didn't add sources corresponding to
predecessors of unreachable blocks. The new strategy employed by the phi
builder creates a phi source for each predecessor and should correctly
handle unreachable blocks by setting those sources to SSA undefs.

Previously, nir_dominance.c didn't properly handle unreachable blocks.
This can happen if, for instance, you have something like this:
loop {
if (...) {
break;
} else {
break;
}
}
In this case, the block right after the if statement will be unreachable.
This commit makes two changes to handle this. First, it removes an assert
and allows block->imm_dom to be null if the block is unreachable. Second,
it properly skips unreachable blocks in calc_dom_frontier_cb.

The KHR_debug spec doesn't actually say we should handle this, but that
is most likely an oversight - it says to check against strlen and
generate errors if length is negative. It appears they just forgot to
explicitly spell out that we should then proceed to actually handle it.

From the KHR_debug spec, section 5.5.5 (Externally Generated Messages):
"If <length> is negative, it is implied that <buf> contains a null
terminated string. The error INVALID_VALUE will be generated if the
number of characters in <buf>, excluding the null terminator when
<length> is negative, is not less than the value of
MAX_DEBUG_MESSAGE_LENGTH."
This indicates that length should be set to strlen for all types, not
just GL_DEBUG_TYPE_MARKER. We want it to be after validate_length()
so we still generate appropriate errors.

obtaining the value of DEBUG_LOGGED_MESSAGES, and the string length

through the value of DEBUG_NEXT_LOGGED_MESSAGE_LENGTH."
Because we weren't including the null terminator, many dEQP tests
called glGetDebugMessageLog with a bufSize parameter that was 1 too
small, and unable to contain the message, so we skipped returning it,
failing many cases.

In many places, the convention is to pass an existing ssadef name ptr
when construction/initializing a new nir_ssa_def. But that goes badly
(as noticed by garbage in nir_print output) when the original string
gets freed.
Just use ralloc_strdup() instead, and add ralloc_free() in the two
places that would care (not that the strings wouldn't eventually get
freed anyways).
Also fixup the nir_search code which was directly setting ssadef->name
to use the parent instruction as memctx.
