If the end of the block is reached during the scan, check
the live ins of the successors. This was already done in the
other direction if the block entry was reached.

Use VOP3 add/addc like usual.
This has some tradeoffs. Inline immediates fold
a little better, but other constants are worse off.
SIShrinkInstructions could be made smarter to handle
these cases.
This allows us to avoid selecting scalar adds where we
need to track the carry in scc and replace its users.
This makes it easier to use the carryless VALU adds.

Currently the default C calling convention functions are treated
the same as compute kernels. Make this explicit so the default
calling convention can be changed to a non-kernel.
Converted with perl -pi -e 's/define void/define amdgpu_kernel void/'
on the relevant test directories (and undoing in one place that actually
wanted a non-kernel).

This was causing a variety of test failures when v2i64
is added as a legal type.
SIFixSGPRCopies should correctly handle the case of vector inputs
to a scalar reg_sequence, so this isn't necessary anymore. This
was hiding some deficiencies in how reg_sequence is handled later,
but this shouldn't be a problem anymore since the register class
copy of a reg_sequence is now done before the reg_sequence.
