Although the first pattern match wins in the sense that no later
function can match the *old* gimple statement, it still seems worth
letting them match the *new* gimple statements, just like we would if
the original IR had included that sequence from the outset.

This is mostly true after the later patch for PR85694, where e.g. we
could recognise:

   signed char a;
   int ap = (int) a;
   int res = ap * 3;

as the pattern:

   short ap' = (short) a;
   short res = ap' * 3;     // S1: definition statement
   int res = (int) res;     // S2: pattern statement

and then apply the mult pattern to "ap' * 3".  The patch needs to
come first (without its own test cases) so that the main over-widening
patch doesn't regress anything.

Make sure that gimple and RTL IRs don't have debug markers before
labels.  When we build the CFG, we move labels before any markers
appearing before them.  Then, make sure we don't mistakenly
reintroduce them.

This reverts some of the complexity that had been brought about by the
initial SFN patches.

From-SVN: r255895

This patch adjusts numerous parts of the compiler that would
malfunction should they find debug markers at points where they may be
introduced.  The changes purport to allow the compiler to pass
bootstrap-debug-lean (-fcompare-debug in stage3) at various
optimization levels, as well as bootstrap-debug-lib (-fcompare-debug
for target libraries), even after the compiler is changed so that
debug markers are introduced in code streams at spots where earlier
debug stmts, insns and notes wouldn't normally appear.

This patch depends on an earlier SFN boilerplate patch, and on another
SFN patch that introduces new RTL insn-walking functions.
