Takashi Yano 34876c05a5 frexpl: Support smaller long double of LDBL_MANT_DIG == 53.
- Currently, frexpl() supports only the following cases.
    1) LDBL_MANT_DIG == 64 or 113
    2) 'long double' is equivalent to 'double'
  This patch add support for LDBL_MANT_DIG == 53.

Takashi Yano 48f6c59332 stdio: Fix issue of printing "%La" format with large exp part.
- Currently, printf("%La\n", 1e1000L) crashes with segv due to lack
  of frexpl() function. With this patch, frexpl() function has been
  implemented in libm to solve this issue.
