* src/SDCCsymt.h: added IS_AUTO(symbol) test macro

* src/SDCCopt.c (isLocalWithoutDef),
* src/SDCCicode.c (operandFromSymbol): use the IS_AUTO test macro
which adds a !IS_EXTERN codition. Fixes bugs #877426 and #751703.
(credit to Maarten Brock for patch #949363, on which this is based)
* support/regression/tests/bug-751703.c: some test cases of extern used
within inner scopes.
