The patch re-factors libgcov.c to make it better modulelized.
It contains two pieces of work:
1. break gcov_exit() into the following structure:
gcov_exit()
--> gcov_exit_compute_summary()
--> allocate_filename_struct()
for gi_ptr in gcov_list
--> gcov_exit_dump_gcov()
--> gcov_exit_open_gcda_file()
--> gcov_exit_merge_gcda ()
--> gcov_exit_merge_summary ()
--> gcov_exit_write_gcda ()
2. split libgcov.c into the following files:
libgcov-profiler.c
libgcov-merge.c
libgcov-interface.c
libgcov-driver.c
libgcov-driver-system.c (source included into libgcov-driver.c)

parallel profiledbootstrap builds of gcc.
This patch addresses the bogus "Invocation mismatch" messages seen in parallel
profiledbootstrap builds of gcc. See PR bootstrap/55051 for a discussion of
why this is occurring and why this checking is inaccurate. Leave it in when
!GCOV_LOCKED, to warn about concurrent update issues requiring locking.

This fixes part of the issue described in PR gcov-profile/54487 where
there were warnings about mismatches due to slight differences in the
merged histograms in different object files. This can happen due to
the truncating integer division in the merge routine, which could result
in slightly different histograms when summaries are merged in different
orders.

Enhances the gcov program summary by adding a histogram of arc counter
entries. This is used to compute working set information in the compiler
for use by optimizations that need information on hot vs cold counter
values or the rough working set size in terms of the number of counters.
Each working set data point is the minimum counter value and number of
counters required to reach a given percentage of the cumulative counter
sum across the profiled execution (sum_all in the program summary).

collect...
This patch adds functionality to libgcov to enable user applications to
collect profile data only in regions of interest. This is useful, for
example, to collect profile data from a long-running server only
during the time when it is serving requests.
Specifically, the new routines __gcov_reset will clear all profile counters
to zero and __gcov_dump will write out the profile information collected so
far. A global variable is used to prevent writing out the profile a
second time during exit.
