These places where probably trying to use the default bitmap obstack,
but passing 0 to bitmap_initialize actually uses gc allocation. In any
case they are all cleaned up before going out of scope so using
auto_bitmap should be fine.

This gets rid of one allocation per bitmap. Often the bitmap_head is
now on the stack, when it isn't its part of some other struct on the
heap instead of being refered to by that struct. On 64 bit platforms
this will increase the size of such structs by 24 bytes, but its an over
all win since we don't need an 8 byte pointer pointing at the
bitmap_head. Given that the auto_bitmap owns the bitmap_head anyway we
know there would never be a place where two auto_bitmaps would refer to
the same bitmap_head object.

With high -j parallelism the autofdo tests can randomly fail.
autofdo uses Linux perf to record profiling data.
Linux perf uses a locked perf buffer. By default it has
around 516k buffer per uid (/proc/sys/kernel/perf_event_mlock_kb).
An individual perf record tries to grab the full 516k,
which makes parallel perf record fail.
This patch limits the perf buffer for individual perf record to 8k.
With the default settings this allows a parallelism of the test
cases of 16, which is hopefully good enough
(if not would need to add some kind of semaphore, or ask
the user to increase the limit as root)
I also removed an unneeded -o perf.data option
Thanks to Marcin to finally spotting the problem.
Passes bootstrap and test on x86_64-linux. Ok for trunk?

On MIPS, SIGABRT is defined like this:
#define SIGIOT 6
#define SIGABRT SIGIOT
This breaks addsig which tries to append __SIGIOT_ to SIGLIST. Signal
number 6 is later added to the output and go complains about a
duplicate signal number.
Fix by recursing once when obtaining the signal number from
gen-sysinfo.go if the signal is defined as an alias of another signal.
Also modify the sed expression to 's/.* = //' which is equivalent to
the original expression but is less misleading given that it might not
match a number.
