The current layout algorithm tries to put consecutive blocks together,
so the priority of the successor block is higher than the priority of
the zero indegree block. This algorithm is beneficial for subsequent
register allocation, but will result in more branch instructions.
The depth-first topological sorting algorithm is a well-known layout
algorithm, which has applications in many languages, and it helps to
reduce branch instructions. This CL applies it to the layout pass.
The test results show that it helps to reduce the code size.
This CL also includes the following changes:
1, Removed the primary predecessor mechanism. The new layout algorithm is
not very friendly to register allocator in some cases, in order to adapt
to the new layout algorithm, a new primary predecessor selection strategy
is introduced.
2, Since the new layout implementation may place non-loop blocks between
loop blocks, some adaptive modifications have also been made to looprotate
pass.
3, The layout also affects the results of codegen, so this CL also adjusted
several codegen tests accordingly.
It is inevitable that this CL will cause the code size or performance of a
few functions to decrease, but the number of cases it improves is much larger
than the number of cases it drops.
