Alok Kumar Sharma c2fd7faea8 Fix for incorrect breakpoint set in case of flang compiled binary
Currently, GDB is not able to set a breakpoint at subprogram post
prologue for flang generated binaries. This is due to clang having
two line notes one before and another after the prologue.
  Now the end of prologue is determined using symbol table, which was
the way for clang generated binaries already. Since clang and flang
both share same back-end it is true for flang as well.

gdb/ChangeLog

      * amd64-tdep.c (amd64_skip_prologue): Using symbol table
      to find the end of prologue for flang compiled binaries.
      * arm-tdep.c (arm_skip_prologue): Likewise.
      * i386-tdep.c (i386_skip_prologue): Likewise.
      * producer.c (producer_is_llvm): New function.
      (producer_parsing_tests): Added new tests for clang/flang.
      * producer.h (producer_is_llvm): New declaration.

gdb/testsuite/ChangeLog

      * gdb.fortran/vla-type.exp: Skip commands not required for
      the Flang compiled binaries after prologue fix.

Internal and external ICC versions have to be taken into account.
PRODUCER strings for internal releases are slightly different than
for public ones. Internal releases have a major release number and
0 as minor release. External releases have 4 fields, 3 of them are
not 0 and only two are of interest, major and update.
Examples are:
Public release:
"Intel(R) Fortran Intel(R) 64 Compiler XE for applications
running on Intel(R) 64, Version 14.0.1.074 Build 20130716";
"Intel(R) C++ Intel(R) 64 Compiler XE for applications
running on Intel(R) 64, Version 14.0.1.074 Build 20130716";
