compiler: add slice initializers to the GC root list
As of https://golang.org/cl/32917 we can put slice initializers in the
.data section. The program can still change the values in those
slices. That means that if the slice elements can contain pointers,
we need to register the entire initializer as a GC root.
This would be straightforward except that we only have a Bexpression
for the slice initializer, not an Expression. So introduce a
Backend_expression type that wraps a Bexpression as an Expression.
The test case for this is https://golang.org/cl/33790.

runtime: print C functions in traceback
Since gccgo can trace back through C code as easily as Go code, we
should print C functions in the traceback.
This worked before https://golang.org/cl/31230 for a dumb reason. The
default value for runtime.traceback_cache was, and is, 2 << 2, meaning
to print all functions. The old C code for runtime_parsedebugvars
would return immediately and do nothing if the environment variable
GODEBUG was not set (if GODEBUG was set it would later call
setTraceback. The new Go code for runtime.parsedebugvars does not
return immediately if GODEBUG is not set, and always calls
setTraceback. Either way, if GOTRACEBACK is not set, setTraceback
would set traceback_cache to 1 << 2, meaning to only print non-runtime
functions and having the effect of not printing plain C functions.
Keep the current handling of GODEBUG/GOTRACEBACK, which matches the gc
library, but add an extra check to print C functions by default.

ira: Don't substitute into TRAP_IF insns (PR78610)
In the testcase, IRA propagates a constant into a TRAP_IF insn, which
then becomes an unconditional trap. Unconditional traps are control
flow insns so doing this requires surgery on the cfg. We cannot do
that here, so instead refuse to do the substitution.

runtime: fixes for -buildmode=c-archive
With -buildmode=c-archive, initsig is called before the memory
allocator has been initialized. The code was doing a memory
allocation because of the call to funcPC(sigtramp). When escape
analysis is fully implemented, that call should not allocate. For
now, finesse the issue by calling a C function to get the C function
pointer value of sigtramp.
When returning from a call from C to a Go function, a deferred
function is run to go back to syscall mode. When the call occurs on a
non-Go thread, that call sets g to nil, making it impossible to add
the _defer struct back to the pool. Just drop it and let the garbage
collector clean it up.

substring locations and # line directives (PR preprocessor/78569)
The ICE in PR preprocessor/78569 appears to be due to an attempt to
generate substring locations in a .i file where the underlying .c file
has changed since the .i file was generated.
This can't work, so it seems safest for the on-demand substring
locations to be unavailable for such files, falling back to
"whole string" locations for such cases.
