03d7993176 - Make this work on systems where the stack is non executable: 
put the to-be-modified insns in an mmap'd page

- Clarify init_function a bit (does not change what it does)

aaacb37226 Clever handling of partially defined equality does not work on 
ppc32/64 at the moment.  Make this test handle that whilst still
testing the facility on x86/amd64.

0307628a86 This was segfaulting on ppc64-linux, even natively. These changes 
stop it doing that.  Am not convinced this is a good fix -- I don't
really understand how this program works.

a9bbc3690b Fix an all-platforms bug introduced by the recent overhaul of function 
interception and wrapping.  This was causing failures matching
function names in suppressions to function names in backtraces when
the latter names were Z-encoded (eg malloc), which typically caused
all leak suppressions to fail because they contain names such as
malloc, which are Z-encoded.

f0d678baab These files all speak about instrumentation functions.

032abb3cdf Rewrite VG_(translate) to make it clearer (it had grown like Topsy for 
a long time) and to use the new preable-generating callback facility
supported by Vex.  Use this to add support for R2 saving/restoring

e626b54566 Tidy up ELF symbol table reading a bit. Make a completely new 
function for reading ELF symbol tables on ppc64-linux so as to avoid
cluttering up the {x86,amd64,ppc32}-linux cases with convoluted
hoop-jumping needed to handle both the dotful (older) and dotless
(newer) ppc64-linux ABI variants.

63da307b46 Use VG_(am_mmap_anon_float_valgrind) to allocate the unredirected

which it isn't when it is allocated as a static variable in the data
