* dwarf2read.c (dwarf2_get_pc_bounds): Require HIGH strictly higher
than LOW. Comment it.
(read_partial_die): Call complaint for inappropriate zero LOWPC or
HIGHPC not strictly higher than LOWPC.

* gdb.dwarf2/dw2-empty-pc-range.S: New file.
* gdb.dwarf2/dw2-empty-pc-range.exp: New file.
* gdb.dwarf2/pr11465.S: New .text labels text_start and text_end.
Provide a stub byte there.
(DW_TAG_compile_unit): Set DW_AT_low_pc, DW_AT_high_pc and
