After installing the patch that enables SSA coalescing of all
variables, I've experienced some compilation errors in Ada, having to
do with EH tables.

As it turns out, the compiler was not ready for such coalescing of
gimple registers.  It created situations in which, because of the
abnormal setjmp/longjmp edges used for EH in the (stage1?) Ada
compiler, we'd get variables that were gimple registers and that had
multiple live versions simultaneously renamed at the time of
inlining.  This should never happen.

This patch arranges for us to note the correct variable version to use
at the new edges for such gimple registers, instead of incorrectly
relying on renaming to do that.
