Craig Topper 87f78cfe15 [X86] In OptimizeLEAs pass, check that the key is in the LEAs map before accessing 
When the key is not already in the map, the access operator[] creates an empty value and grows the map.
Resizing a map is very slow, so this needs to be avoided.

Found with csmith + asserts.
