||[AArch64] Fix symbol offset limit
In aarch64_classify_symbol symbols are allowed large offsets on relocations.
This means the offset can use all of the +/-4GB offset, leaving no offset
available for the symbol itself. This results in relocation overflow and
link-time errors for simple expressions like &global_array + 0xffffff00.
To avoid this, unless the offset_within_block_p is true, limit the offset
to +/-1MB so that the symbol needs to be within a 3.9GB offset from its
references. For the tiny code model use a 64KB offset, allowing most of
the 1MB range for code/data between the symbol and its references.
* config/aarch64/aarch64.c (aarch64_classify_symbol):
Apply reasonable limit to symbol offsets.
* gcc.target/aarch64/symbol-range.c: Improve testcase.
* gcc.target/aarch64/symbol-range-tiny.c: Likewise.
