Daily bump.

From-SVN: r242817

Fix e500 offset handling for TImode.

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.

From-SVN: r242814

Add another e500 subreg pattern.

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:
 }
 ^
(insn 31 30 32 2 (set (reg:DF 203)
        (subreg:DF (reg:TI 202) 8)) "../sysdeps/ieee754/ldbl-128ibm/s_modfl.c":44 -1
     (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.

combine: Convert subreg-of-lshiftrt to zero_extract properly (PR78390)

r242414, for PR77881, introduces some bugs (PR78390, PR78438, PR78477).
It all has the same root cause: that patch makes combine convert every
lowpart subreg of a logical shift right to a zero_extract.  This cannot
work at all if it is not a constant shift, and it has to be a bit more
careful exactly which bits it extracts.

The intent (in combination with later patches) is to move the
handling of the BYTES_BIG_ENDIAN != WORDS_BIG_ENDIAN case into
just two places, so that for other combinations we don't have

Fix bogus failure of uninit-19.c for avr

The test fails for avr because fn1 does not get inlined into fn2. Inlining
occurs for x86_64 because fn1's computed size equals call_stmt_size. For the
avr, 32 bit memory moves are more expensive, and b[3] = p10[a] results in
a bigger size for fn1, preventing the inlining.

Add -finline-small-functions to force early inliner to inline fn1.

runtime: rewrite panic/defer code from C to Go

    The actual stack unwind code is still in C, but the rest of the code,
    notably all the memory allocation, is now in Go.  The names are changed
    to the names used in the Go 1.7 runtime, but the code is necessarily
    somewhat different.

    The __go_makefunc_can_recover function is dropped, as the uses of it
    were removed in https://golang.org/cl/198770044.
