Ben Craig acd5ee88df [libcxxabi] Teach cxa_demangle about Hexagon's long double size
cxa_demangle's default size for a long double is 10 bytes. Hexagon
only has an 8 byte long double though.

Ben Craig a6dc36f65e [libcxxabi] Make test tolerant of uncommon floating literal demanglings
libcxxabi uses the C99 library's %a format specifier to turn a floating
point value into a hexadecimal string representation. The %a format
specifier is rather loosely defined in the C spec though, and some C
libraries emit a different (but valid) string for a given floating
point value. In particular, the C spec only requires that there is a
single, non-zero hexadecimal digit on the left of the decimal point.
Given that constraint, there are typically four different valid 
representations of a floating point number. I have updated the test to
accept any of the valid representations for demangled floating
point literals.

This patch re-commits r256322 and r256323. They were reverted due to a OS X
test failure. The test failure has been fixed by libc++ commit r258217.

Logan Chien 338d6de5fa Fix ARM __cxa_end_cleanup() and gc-sections.
This commit adds SHF_ALLOC and SHF_EXECINSTR section flags to
`.text.__cxa_end_cleanup` section.  This fixes a link error when we are
using integrated-as and `ld.gold` (with `-Wl,--gc-sections` and
`-Wl,--fatal-warnings`.)

Detailed Explanation:

1. There might be some problem with LLVM integrated-as.  It is not
   emitting any section flags for text sections.  (This will be fixed in
   an independent commit.)

2. `ld.gold` will skip the external symbols in the section without
   SHF_ALLOC.  This is the reason why `.text.__cxa_end_cleanup_impl`
   section is discarded even though it is referenced by
   `__cxa_end_cleanup()`.

This commit workaround the problem by specifying the section flags
explicitly.

Eric Fiselier 3c9babc55f [libc++abi] Use libgcc and libgcc_s to provide _Unwind symbols instead of libgcc_eh.a
Summary:
libgcc_eh.a cannot be used when building libc++abi as a shared library (the default configuration). See this post for some more discussion: https://gcc.gnu.org/ml/gcc/2012-03/msg00104.html

This patch reverts back to using libgcc_s when linking libc++abi.so.

Saleem Abdulrasool af99cd4174 EH: fix register usage for SjLj
When using SjLj EH, do not use __builtin_eh_return_regno, map directly to the
ID.  This would work on some targets, particularly those where the non-SjLj EH
personality used the same register mapping (0 -> 0, 1 -> 1).  However, this is
not guaranteed.  Avoiding the use of the builtin enables the use of libc++ with
SjLj EH on all targets.
