gdb: Allow prologue detection via symbols for Intel compilers.
The next-gen Intel Fortran compiler isn't flang-based, but emits
prologue_end in the same manner. As do the newer Intel C/C++ compilers.
This allows prologue detection based on dwarf for all newer Intel compilers.
The cut-off version was not chosen for any specific reason other than the
effort to test this.
gdb/Changelog:
2021-04-08 Felix Willgerodt <felix.willgerodt@intel.com>
* i386-tdep.c (i386_skip_prologue): Use symbol table to find the
prologue end for Intel compilers.
* amd64-tdep.c (amd64_skip_prologue): Likewise.
* producer.c (producer_is_icc_ge_19): New function.
* producer.h (producer_is_icc_ge_19): New declaration.
