i386 testsuite: cope with --enable-default-pie

Running the testsuite on a toolchain build with --enable-default-pie
had some unexpected fails.  Adjust the tests to tolerate the effects
of this configuration option on x86_64-linux-gnu and i686-linux-gnu.

The cet-sjlj* tests get offsets before the base symbol name with PIC
or PIE.  A single pattern covering both alternatives somehow triggered
two matches rather than the single expected match, thus my narrowing
the '.*' to not skip line breaks, but that was not enough.  Still
puzzled, I separated the patterns into nonpic and !nonpic, and we get
the expected matchcounts this way.

Tests for -mfentry require an mfentry effective target, which excludes
32-bit x86 with PIC or PIE enabled, that's why the patterns that
accept the PIC sym@RELOC annotations only cover x86_64.  mvc7 is
getting regexps extended to cover PIC reloc annotatios and all of the
named variants, and tightened to avoid unexpected '.' matches.

The pr24414 test stores in an unadorned named variable in an old-style
asm statement, to check that such asm statements get an implicit
memory clobber.  Rewriting the asm into a GCC extended asm with the
variable as an output would remove the regression it checks against.
Problem is, the literal reference to the variable is not PIC, so it's
rejected by the elf64 linker with an error, and flagged with a warning
by the elf32 one.  We could presumably make the variable references
PIC-friendly with #ifdefs, but I doubt that's worth the trouble.  I'm
just arranging for the test to be skipped if PIC or PIE are enabled by
default.
