Subject: grep: move is_fixed() earlier to avoid forward declaration
X-Git-Tag: v2.14.0-rc0~124^2~5

grep: move is_fixed() earlier to avoid forward declaration

Move the is_fixed() function which are currently only used in
compile_regexp() earlier so it can be used in the PCRE family of
functions in a later change.
