Instead of trying to expand whole range at regcomp() stage as we do,
GNU regex allocates separate ranges [start,end] set each character
is checked against, so collation is possible and turned on for ranges here.
When something like that will be implemented or our obsoleted regex code
will be replaced to something like TRE, and in case we decide to use
collation in [a-z] ranges, all changes related to r302512 can be backed out,
but now we need consistency.
glob() here too.
I try to keep the change minimal to not touch contribed code much.
I'll send it upstream when it will be merged to the main branches,

This may be reworked upstream but in the interim should address the

POSIX basename() and dirname() are allowed to overwrite the input
buffer. The advantage of implementing it that way is that the functions
can be thread-safe, as they don't store the result in a global buffer.
It looks like ATF wants to call basename() and dirname() in the
non-standard way where the argument is of type "const char *". This
change disables the calls to basename() and dirname(), which only seems
to affect the formatting of some rare debug/error messages.

Only attempt to detect AVG if SSE2 is available
Summary:
In PR29973 Sanjay Patel reported an assertion failure when a certain
loop was optimized, for a target without SSE2 support. It turned out
this was because of the AVG pattern detection introduced in rL253952.
Prevent the assertion failure by bailing out early in
`detectAVGPattern()`, if the target does not support SSE2.
Also add a minimized test case.
