gdb: Add maint set ignore-prologue-end-flag
The previous patch added support for the DWARF prologue-end flag in line
table. This flag can be used by DWARF producers to indicate where to
place breakpoints past a function prologue. However, this takes
precedence over prologue analyzers. So if we have to debug a program
with erroneous debug information, the overall debugging experience will
be degraded.
This commit proposes to add a maintenance command to instruct GDB to
ignore the prologue_end flag.
Tested on x86_64-gnu-linux.
