Properly check conflict between DRAP register and __builtin_eh_return

Since %ecx can't be used for both DRAP register and __builtin_eh_return,
we need to check if crtl->drap_reg uses %ecx before using %ecx for
__builtin_eh_return.

PR target/70439
* config/i386/i386.c (ix86_expand_epilogue): Properly check
conflict between DRAP register and __builtin_eh_return.
