Add gmonster-{1,2} perf testcases. 

These testcases are mocks of real programs.
GDB doesn't care what the programs do, they just have to look
and/or behave like the real program.
These testcases exercise gdb when debugging really large programs.
E.g., gmonster-1 has 10,000 CUs, and gmonster-2 has 1000 shared libs
(which is actually a little small, 5000 would be more accurate).

# Perftest description file for building the "gmonster1" benchmark.
# Where does the name come from? The benchmark is derived from one of the
# monster programs at Google.
#
# Perftest descriptions are loaded thrice:
# 1) To generate the build .exp files
# GDB_PERFTEST_MODE=gen-build-exps
# This step allows for parallel builds of the majority of pieces of the
# test binary and shlibs.
# 2) To compile the "pieces" of the binary and shlibs.
# "Pieces" are the bulk of the machine-generated sources of the test.
# This step is driven by lib/build-piece.exp.
# GDB_PERFTEST_MODE=build-pieces
# 3) To perform the final link of the binary and shlibs.
# GDB_PERFTEST_MODE=compile
#
# Example usage:
# bash$ make -j5 build-perf RUNTESTFLAGS="gmonster1.exp gmonster2.exp"
# bash$ make check-perf RUNTESTFLAGS="gdb.perf/gm*-*.exp GDB=/path/to/gdb"
