b178ecbbc0 Fix infinite recursion for when extract_vector_elt is legal. Unfortunately no public targets use this code-path, so no test.

513dcba4f8 Remove X86ISD::LOAD_PACK and X86ISD::LOAD_UA and associated code from the 
x86 target, replacing them with the new alignment attributes on memory
references.

e8170a07f8 Heal EH handling stuff by emitting correct offsets to callee-saved registers. 
Pretty hackish, but code itself is dirty mess, so we won't make anything worse. :)

6286ca1d69 Add better verification of attributes on function types. It is not permitted 
to use sret or inreg on the function. It is equally illegal to use noreturn
or nounwind on a parameter; they only go with the function. This patch
enforces these rules.

5a29993695 The Ada f-e produces various auxiliary output files 
that cannot be suppressed and cannot be redirected:
they are dumped in the current working directory.
When running the testsuite this means that these
files do not end up in the Output directory.  The
best solution I could find is to change directory
into Output before running tests.

ec44ba07b5 For multipart tests, place the parts with no 
RUN line in Support.  Give up on sending output
to /dev/null - this cannot always be arranged.
