[PATCH] Fix bug in hoisting when using -fgcse-las

[Maxim Kuvyrkov]

This patch fixes http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45107 .

The problem is due to mismatch in max_distance values for the same 
expression when it is processed on the LHS versus the RHS.

More specifically, the problem due to me not including -fgcse-las in the 
testing of hoisting improvements patches.

The attached patch fixes the bug.  It was tested by bootstrapping GCC 
with -fgcse-las in BOOT_CFLAGS.

OK to apply?
