[PATCH v5 0/7] Clean gdb.base when testing with clang

[Bruno Larsen <blarsen@redhat.com>]

When testing GDB with clang, gdb.base had over 50 more failures than when
testing with gcc.  Examining the failed tests led to a few clang bugs, a
few GDB bugs, and many testsuite assumptions that could be changed.

After this patch series, nothing should be changed for testing with gcc,
and testing with clang should only show non-trivial failures for
maint.exp and macscp.exp, along with the same GCC failures.

Changes in v5:
    * Removed patches previously numbered 1,4-11 given Andrew's approval
    * Split previous patch 3 in two, to make it more focused
    * Reworded some commits
    * Dropped patch 13, in favor of Andrew's suggestion (not included).

Changes in v4:
    * Added new test to step through a function's epoligue
    * renamed gdb_step_until_regexp -> gdb_step_until
    * small style and wording changes in patches 1 and 2
    * Dropped patch 3 - no longer necessary
    * patch 4 was reworked based on Andrew's suggestion
small note, Andrew has OK'd patched 5 and 6 (currently 4 and 5) in v3;

Changes in v3:
    * Fixed some issues that only showed up on CXX_FOR_TARGET=clang
    * rebased on current master

Changes in v2:
    * Introduced gdb_step_until_regexp, based on Pedro's and Andrew's suggestions
    * reworked fixes for: skip.exp, skip-solib.exp and msym-bp-shl.exp
    * Used Pedro's suggestion for call-ar-st
    * reordered patches slightly
