[gdb/symtab] Workaround PR gas/31115
On arm-linux, with gas 2.40, I run into:
...
(gdb) x /i main+8^M
0x4e1 <main+7>: vrhadd.u16 d14, d14, d31^M
(gdb) FAIL: gdb.arch/pr25124.exp: disassemble thumb instruction (1st try)
...
This is a regression due to PR gas/31115, which makes gas produce a low_pc
with the thumb bit set (0x4d8 & 0x1):
...
<1><24>: Abbrev Number: 2 (DW_TAG_subprogram)
<25> DW_AT_name : main
<29> DW_AT_external : 1
<29> DW_AT_type : <0x2f>
<2a> DW_AT_low_pc : 0x4d9
<2e> DW_AT_high_pc : 12
...
The regression was introduced in 2.39, and is also present in 2.40 and 2.41,
and hasn't been fixed yet.
Work around this in read_func_scope, by using gdbarch_addr_bits_remove on
low_pc and high_pc.
Tested on arm-linux and x86_64-linux.
