Given my previous fix for a missing insn pattern for e500, building
glibc runs into an assembler error "Error: operand out of range (256
is not between 0 and 248)". This comes from an insn:
(insn 115 1209 1210 (set (reg:DF 27 27 [orig:294 _129 ] [294])
(subreg:DF (mem/c:TI (plus:SI (reg/f:SI 1 1)
(const_int 256 [0x100])) [14 %sfp+256 S16 A128]) 0)) 1909 {*frob_df_ti}
(nil))
This patch adjusts the offset handling for TImode - and TDmode and
PTImode in case such subregs can arise for them - to be the same as
for TFmode, so that proper SPE offset checks are made in the
TARGET_E500_DOUBLE case.
This allows the glibc build to complete. Testing shows 372 FAILs
across the gcc, g++ and libstdc++ testsuites; more cleanup is
certainly needed, but this gets to the point where the toolchain at
least builds so it's possible to compare test results when fixing
bugs.
* config/rs6000/rs6000.c (rs6000_legitimate_offset_address_p): For
TARGET_E500_DOUBLE. handle TDmode, TImode and PTImode the same as
TFmode, IFmode and KFmode.

Building glibc for powerpc-linux-gnuspe --enable-e500-double, given
the patch <https://gcc.gnu.org/ml/gcc-patches/2016-11/msg02404.html>
applied, fails with errors such as:
../sysdeps/ieee754/ldbl-128ibm/s_modfl.c: In function '__modfl':
../sysdeps/ieee754/ldbl-128ibm/s_modfl.c:91:1: error: unrecognizable insn:

(nil))
../sysdeps/ieee754/ldbl-128ibm/s_modfl.c:91:1: internal compiler error: in extract_insn, at recog.c:2311
This patch adds an insn pattern similar to various patterns already
present to handle extracting such a subreg. This allows the glibc
build to get further, until it runs into an assembler error for which
I have another patch.

it can make worse code if the result will need reloads.
