[gdb/symtab] Improve invalid range check in create_addrmap_from_gdb_index
When running test-case gdb.tui/tui-missing-src.exp with target board
gold-gdb-index (and likewise fission and fission-dwp) on aarch64-linux, I run
into:
...
FAIL: gdb.tui/tui-missing-src.exp: checking if inside f2 ()
...
Looking at the gold-gdb-index case, the problem is caused by the address table
of the .gdb_index section:
...
Address table:
000000000040066c 0000000000400694 0
000000000040053f 0000000000400563 1
...
The address range for f2 is [0x400694, 0x4006b8), but the address table says
it's [0x40053f, 0x400563).
The address 0x40053f is not even in a section:
...
[Nr] Name Type Address Off Size ES Flg Lk Inf Al
...
[12] .plt PROGBITS 00000000004004b8 0004b8 000050 10 AX 0 0 8
[13] .text PROGBITS 0000000000400540 000540 000178 00 AX 0 0 64
...
but part of the hole [0x400508, 0x400540) in between .plt and .text.
Detect this in the invalid range check in create_addrmap_from_gdb_index.
Tested on aarch64-linux.
