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.

In check_effective_target_freorder we check to see if the target
supports -freorder-blocks-and-partition. However we disable
-freorder-blocks-and-partition when -fprofile-use is not supplied so for
some targets we'll not see any message about lack of support for
-freorder-blocks-and-partition unless -fprofile-use is also passed.
This commit extends check_effective_target_freorder to first try
-freorder-blocks-and-partition on its own, then try -fprofile-use and

PR78590 shows a problem in change_zero_ext, where we change a zero_extend
of a subreg to a logical and. We should only do this if the thing we are

of (e.g.) a float in a different size, which is nonsensical and hits an
assert.

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.

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.
