[SPARK-16514][SQL] Fix various regex codegen bugs
## What changes were proposed in this pull request?
RegexExtract and RegexReplace currently crash on non-nullable input due use of a hard-coded local variable name (e.g. compiles fail with `java.lang.Exception: failed to compile: org.codehaus.commons.compiler.CompileException: File 'generated.java', Line 85, Column 26: Redefinition of local variable "m" `).
This changes those variables to use fresh names, and also in a few other places.
## How was this patch tested?
Unit tests. rxin
