At startup valgrind fetches the current working directory and stashes
it away to be used later (in debug messages, read config files or create
log files). But if the current working directory didn't exist (or there
was some other error getting its path) then valgrind would go in an
endless loop. This was caused by assuming that any error meant a larger
buffer needed to be created to store the cwd path (ERANGE). However
there could be other reasons calling getcwd failed.
Fix this by only looping and resizing the buffer when the error is
ERANGE. Any other error just means we cannot fetch and store the current
working directory. Fix all callers to check get_startup_wd() returns
NULL. Only abort startup if a relative path needs to be used for
user supplied relative log files. Debug messages will just show
"<NO CWD>". And skip reading any config files from the startup_wd
if it doesn't exist.
Also add a new testcase that tests executing valgrind in a deep,
inaccessible and/or non-existing directory (none/tests/nocwd.vgtest).

none/tests/ppc64/jm_int_isa_2_07.stdout.exp
By convention the file jm_int_isa_2_07.stdout.exp is the big endian reuslts.
If the little endian results differ, the file has -LE appended to it.
This patch replaces the little endian results that are currenttly in
none/tests/ppc64/jm_int_isa_2_07.stdout.exp with the correct the big
endian results.

The LDR (literal, int reg) testcase takes a code label and compares the
instructions around the label with known instructions in the code stream.
There were only fixed insns on either side of the checking instruction
which isn't enough given that offsets of +/-8 are used, instructions are
only 4 wide and the values loaded are 64bit. Newer gcc versions would
generate different code around the label and cause the tests to fail.
Add enough nops around the actual instruction to really give known
expected constant values to check against.

The test none/tests/ppc64/test_isa_2_07.c steps beyond the data array in a
number of places. The issue is the array is declared to be of size N. The for
loop is: for (i=0; i<N; i=i+2). In the body of the loop the array elements
A[i] and A[i+1] are accessed. On the last iteration i=N-1 and the second array
access becomes A[N-1+1] which accesses one element past the declared array
size.
This commit fixes the array bounds by making the for loop read:
for (i=0; i<N-1; i=i+2)
The expected output files
none/tests/ppc64/jm_int_isa_2_07.stdout.exp
